The metamaterial is prepared of permalloy flakes sized from few to 50μ placed into epoxy-amine matrix. Two series of metamaterial samples are under study with the volume portion of permalloy particles 15% and 30%. There is no direct electrical contact between permalloy particles. Microwave measurements have been carried out at frequencies of 12 to 30 GHz in magnetic fields up to 12 kOe. Sharp decrease of transmitted wave is observed under ferromagnetic resonance condition caused by absorption. Under magnetic antiresonance condition, in opposite, maximum of reflection coefficient is observed at frequencies exceeding 30 GHz. For example, for metamaterial sample with the volume portion of permalloy of 30%, the variation of reflection coefficient in magnetic field reaches 300%. These high variations are of interest to develop magnetic field driven microwave devices. Magnetic field variations of refractive index are also estimated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ferromagnetic%20resonance" title="ferromagnetic resonance">ferromagnetic resonance</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20antiresonance" title=" magnetic antiresonance"> magnetic antiresonance</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20metamaterials" title=" microwave metamaterials"> microwave metamaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=permalloy%20flakes" title=" permalloy flakes"> permalloy flakes</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20and%20reflection%20coefficients" title=" transmission and reflection coefficients"> transmission and reflection coefficients</a> </p> <a href="https://publications.waset.org/abstracts/102593/microwave-transmission-through-metamaterial-based-on-permalloy-flakes-under-magnetic-resonance-and-antiresonance-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102593.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">140</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1415</span> Vertical and Lateral Vibration Response for Corrugated Track Curves Supported on High-Density Polyethylene and Hytrel Rail Pads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.M.%20Balekwa">B.M.

Fourie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modal analysis is applied to establish the dynamic difference between vibration response of the rails supported on High Density Polyethylene (HDPE) and Hytrel/6358 rail pads. The experiment was conducted to obtain the results in the form of Frequency Response Functions (FRFs) in the vertical and lateral directions. Three antiresonance modes are seen in the vertical direction; one occurs at about 150 Hz when the rail resting on the Hytrel/6358 pad experiences a force mid-span. For the rail resting on this type of rail pad, no antiresonance occurs when the force is applied on the point of the rail that is resting on the pad and directly on top of a sleeper. The two antiresonance modes occur in a frequency range of 250 – 300 Hz in the vertical direction for the rail resting on HDPE pads. At resonance, the rail vibrates with a higher amplitude, but at antiresonance, the rail transmits vibration downwards to the sleepers. When the rail is at antiresonance, the stiffness of the rail pads play a vital role in terms of damping the vertical vibration to protect the sleepers. From the FRFs it is understood that the Hytrel/6358 rail pads perform better than the HDPE in terms of vertical response, given that at a lower frequency range of 0 – 300 Hz only one antiresonance mode was identified for vertical vibration of the rail supported on Hytrel/6358. This means the rail is at antiresonance only once within this frequency range and this is the only time when vibration is transmitted downwards. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accelerance" title="accelerance">accelerance</a>, <a href="https://publications.waset.org/abstracts/search?q=FRF" title=" FRF"> FRF</a>, <a href="https://publications.waset.org/abstracts/search?q=rail%20corrugation" title=" rail corrugation"> rail corrugation</a>, <a href="https://publications.waset.org/abstracts/search?q=rail%20pad" title=" rail pad"> rail pad</a> </p> <a href="https://publications.waset.org/abstracts/125399/vertical-and-lateral-vibration-response-for-corrugated-track-curves-supported-on-high-density-polyethylene-and-hytrel-rail-pads" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125399.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">177</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1414</span> Magnetic Nanoparticles for Cancer Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sachinkumar%20Patil">Sachinkumar Patil</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonali%20Patil"> Sonali Patil</a>, <a href="https://publications.waset.org/abstracts/search?q=Shitalkumar%20Patil"> Shitalkumar Patil</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nanoparticles played important role in the biomedicine.

But this leads to a dead end in traditional physics, and quantum explanations must be referred to explain the magnetic phenomenon. However, a study of magnetic lines as percussive waves leads to other paths capable of interpreting magnetism through traditional physics. Methodology: Brick used in the experiment: two parallel electric current cables attract each other if current goes in the same direction and its application at a microscopic level inside magnets. Significance: Consideration of magnetic lines as magnets themselves would mean a paradigm shift in the study of magnetism and open the way to provide solutions to mysteries of magnetism until now only revealed by quantum mechanics. Major findings: discover how a magnetic field is created, as well as reason how magnetic attraction and repulsion work, understand how magnets behave when splitting them, and reveal the impossibility of a Magnetic Monopole. All of this is presented as if it were a symphony in which all the notes fit together perfectly to create a beautiful, smart, and simple work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20lines%20of%20force" title="magnetic lines of force">magnetic lines of force</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title=" magnetic field"> magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20attraction%20and%20repulsion" title=" magnetic attraction and repulsion"> magnetic attraction and repulsion</a>, <a href="https://publications.waset.org/abstracts/search?q=magnet%20split" title=" magnet split"> magnet split</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20monopole" title=" magnetic monopole"> magnetic monopole</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20lines%20of%20force%20as%20magnets" title=" magnetic lines of force as magnets"> magnetic lines of force as magnets</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20lines%20of%20force%20as%20waves" title=" magnetic lines of force as waves"> magnetic lines of force as waves</a> </p> <a href="https://publications.waset.org/abstracts/172916/consideration-of-magnetic-lines-of-force-as-magnets-produced-by-percussion-waves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172916.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">90</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1410</span> Magnetic and Optical Properties of GaFeMnN</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.Abbad">A.Abbad</a>, <a href="https://publications.waset.org/abstracts/search?q=H.A.Bentounes"> H.A.Bentounes</a>, <a href="https://publications.waset.org/abstracts/search?q=W.Benstaali"> W.Benstaali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The full-potential linearized augmented plane wave method (FP-LAPW) within the Generalized Gradient Approximation (GGA) is used to calculate the magnetic and optical properties of quaternary GaFeMnN.

Various configurations of Mn sites and Si and C vacancies were considered. The magnetic coupling between the two Mn atoms at substitutional and interstitials sites with and without vacancies is studied as a function of Mn atoms interatomic distance. It was found that the magnetic interaction energy decreases with increasing distance between the magnetic atoms. The energy levels appearing in the band gap due to vacancies and due to Mn impurities are determined. The calculated DOS’s are used to analyze the nature of the exchange interaction between the impurities. The band coupling model based on the p-d and d-d level repulsions between Mn and SiC has been used to describe the magnetism observed in each configuration.

These bioassays can further be integrated with other laboratory components to form a biosensor which can be used for cell sorting, mixing, purification, transport, manipulation etc. These bio-sensing applications have also been facilitated by the wide availability of magnetic beads which range in size and magnetic properties produced by different manufacturers. In order to improve the efficiency and separation capabilities of these biosensors, it is important to determine the magnetic force induced velocities and interaction of beads within the magnetic field; this will help biosensor users choose the desired magnetic bead for their specific application. This study presents for the first time the interaction between a pair of different sized super-paramagnetic beads suspended in a static fluid moving within a uniform magnetic field using a modified finite-time-finite-difference scheme. A captured video was used to record the trajectory pattern and a good agreement was obtained between the simulated trajectories and the video data. The model is, therefore, a good approximation for predicting the velocities as well as the interaction between various magnetic particles which differ in size and magnetic properties for bio-sensing applications requiring a low concentration of magnetic beads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosensor" title="biosensor">biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title=" magnetic field"> magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20separation" title=" magnetic separation"> magnetic separation</a>, <a href="https://publications.waset.org/abstracts/search?q=super-paramagnetic%20bead" title=" super-paramagnetic bead"> super-paramagnetic bead</a> </p> <a href="https://publications.waset.org/abstracts/40063/comparison-between-simulation-and-experimentally-observed-interactions-between-two-different-sized-magnetic-beads-in-a-fluidic-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40063.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">473</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1407</span> Magnetic Field Induced Tribological Properties of Magnetic Fluid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kinjal%20Trivedi">Kinjal Trivedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20V.%20Upadhyay"> Ramesh V.

In present work, four ball tester has been used to investigate the tribological properties of the magnetic fluid having a 4 wt% of nanoparticles. The structural characterization of fluid shows crystallite size of particle is 11.7 nm and particles are nearly spherical in nature. The magnetic characterization shows the fluid saturation magnetization is 2.2 kA/m. The magnetic field applied using permanent strip magnet (0 to 1.6 mT) on the faces of the lock nut and fixing a solenoid (0 to 50 mT) around a shaft, such that shaft rotates freely. The magnetic flux line for both the systems analyzed using finite elemental analysis. The coefficient of friction increases with the application of magnetic field using permanent strip magnet compared to zero field value. While for the solenoid, it decreases at 20 mT. The wear scar diameter is lower for 1.1 mT and 20 mT when the magnetic field applied using permanent strip magnet and solenoid, respectively. The coefficient of friction and wear scar reduced by 29 % and 7 % at 20 mT using solenoid. The worn surface analysis carried out using Scanning Electron Microscope and Atomic Force Microscope to understand the wear mechanism. The results are explained on the basis of structure formation in a magnetic fluid upon application of magnetic field. It is concluded that the tribological properties of magnetic fluid depend on magnetic field and its applied direction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=four%20ball%20tester" title="four ball tester">four ball tester</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20fluid" title=" magnetic fluid"> magnetic fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=nanolubricant" title=" nanolubricant"> nanolubricant</a>, <a href="https://publications.waset.org/abstracts/search?q=tribology" title=" tribology"> tribology</a> </p> <a href="https://publications.waset.org/abstracts/88005/magnetic-field-induced-tribological-properties-of-magnetic-fluid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88005.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">235</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1406</span> Road Vehicle Recognition Using Magnetic Sensing Feature Extraction and Classification </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiao%20Chen">Xiao Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaoying%20Kong"> Xiaoying Kong</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20Xu"> Min Xu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a road vehicle detection approach for the intelligent transportation system.

To demonstrate the effect of MF’s on mass transfer, the calcium carbonate precipitation process was selected. To the vessel with attached conductometric probes and placed inside the generator, specific doses of calcium chloride and sodium carbonate were added. Electrical conductivity changes of the mixture inside the vessel were measured over time until equilibrium was established.

An important influence factor on the convergence process is how to determine the relative permeability. An improved method, which ensures the calculation, is convergence by linear iterative method for saturated magnetic field. If there are inflection points on the magnetic curve,an optimum convergence method of solution for nonlinear magnetic field was provided. Then the equivalent magnetic circuit is calculated, and d,q-axis inductance can be got.

Highly monodispersed magnetic nanoparticles with controlled particle size and surface coating have been successfully synthesized as a model system to investigate the effect of surface coating on the T2 relaxivity and specific absorption rate (SAR) under an alternating magnetic field, respectively. Amongst, by using mPEG-g-PEI to solubilize oleic-acid capped 6 nm magnetic nanoparticles, the T2 relaxivity could be significantly increased by up to 4-fold as compared to PEG coated nanoparticles. Moreover, it largely enhances the cell uptake with a T2 relaxivity of 92.6 mM-1s-1 for in vitro cell MRI. As for hyperthermia agent, SAR value increase with the decreased thickness of PEG surface coating. By elaborate optimization of surface coating and particle size, a significant increase of SAR (up to 74%) could be achieved with a minimal variation on the saturation magnetization (<5%). The 19 nm magnetic nanoparticles with 2000 Da PEG exhibited the highest SAR of 930 W•g-1 among the samples, which can be maintained in various simulated physiological conditions.

Basically a Spacecraft is used to attach a large sheet of aluminum on to the surface of the asteroid, the Spacecraft acts as an electro magnet and the induced magnetic field would eventually repel the aluminum intern repelling the asteroid.

These compounds were prepared by the sol-gel method. The refinement of the X-ray diffraction reveals that all samples crystallize in a rhombohedral structure (space group R3 ̅c). Detailed measurements of the magnetization as a function of temperature and magnetic applied field M (µ₀H, T) were carried out. From the M(µ₀H, T) curves, we have calculated the magnetic entropy change (ΔSM) according to the Maxwell relation. The temperature dependence of the magnetization M(T) reveals a decrease of M when increasing the x content. The magnetic entropy change (ΔSM) reaches a maximum value near room temperature. It was also found that this compound exhibits a large magnetocaloric effect MCE which increases when decreasing Ga concentration.

In this present work, we have studied the magnetic and physical properties of the new Gd₂AgSi₃ polycrystalline compound. The sample was synthesized by the arc-melting method and confirmed to crystallize in the tetragonal α-ThSi₂-type crystal structure with space group I4/amd. Dc– and ac–magnetic susceptibility, specific heat, electrical resistivity, and magnetoresistance measurements were performed on the new compound. The structure provides a unique position in the unit cell for the magnetic trivalent Gd ion. Two magnetic phase transitions were consistently found in dc- and ac-magnetic susceptibility, heat capacity, and electrical resistivity at temperatures Tₙ₁ = 11 K and Tₙ₂ = 20 K, which is an indication of the complex magnetic behavior in this compound. The compound is found to be metamagnetic over a range of temperatures below and above Tₙ₁. From field-dependent electrical resistivity, it is confirmed that the compound shows unusual negative magnetoresistance in the antiferromagnetically ordered region. These results contribute to a better understanding of this class of materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20magnetic%20behavior" title="complex magnetic behavior">complex magnetic behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=metamagnetic" title=" metamagnetic"> metamagnetic</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20magnetoresistance" title=" negative magnetoresistance"> negative magnetoresistance</a>, <a href="https://publications.waset.org/abstracts/search?q=two%20magnetic%20phase%20transitions" title=" two magnetic phase transitions"> two magnetic phase transitions</a> </p> <a href="https://publications.waset.org/abstracts/120185/double-magnetic-phase-transition-in-the-intermetallic-compound-gd2agsi3" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120185.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">122</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1395</span> Structural and Magnetic Properties of Mn-Doped 6H-SiC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Al%20Azri">M.

In addition, ab-initio calculations were used to investigate the structural and magnetic properties of Mn-doped 6H-SiC. Various configurations of Mn sites and vacancy types were considered. The calculations showed that a substitutional Mn atom at Si site possesses larger magnetic moment than Mn atom at C site. A model is introduced to explain the dependence of the magnetic structure on site occupation.

The magnetic behaviour of magnetic nanoparticles (NPs) helps them in numerous different ways. The most important amongst them is the ease with which they can be purified and also can be separated from the media in which they are present merely by applying an external magnetic field. This exceptional ease of separation of the magnetic NPs from an aqueous media enables them to use for extracting/removing metal pollutants from complex aqueous medium. Functionalized magnetic NPs can be subjected for the metallic impurities extraction if are favourably adsorbed on the NPs surfaces. We have successfully used the magnetic NPs as vehicles for gold and silver NPs removal from the complex fluids. The NPs loaded with gold and silver NPs pollutant fractions has been easily removed from the aqueous media by using external magnetic field. Similarly, we have used the magnetic NPs for extraction of protein from complex media and then constantly washed with pure water to eliminate the unwanted surface adsorbed components for quantitative estimation. The purified and protein loaded magnetic NPs are best analyzed with SDS Page to not only for characterization but also for separating the protein fractions. A collective review of the results indicates that we have synthesized surfactant coated iron oxide NPs and then functionalized these with selected materials. These surface active magnetic NPs work very well for the extraction of metallic NPs from the aqueous bulk and make the whole process environmentally sustainable. Also, magnetic NPs-Au/Ag/Pd hybrids have excellent protein extracting properties. They are much easier to use in order to extract the magnetic impurities as well as protein fractions under the effect of external magnetic field without any complex conventional purification methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20nanoparticles" title="magnetic nanoparticles">magnetic nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=protein" title=" protein"> protein</a>, <a href="https://publications.waset.org/abstracts/search?q=functionalized" title=" functionalized"> functionalized</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a> </p> <a href="https://publications.waset.org/abstracts/122882/functionalized-magnetic-iron-oxide-nanoparticles-for-extraction-of-protein-and-metal-nanoparticles-from-complex-fluids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122882.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1391</span> Computer Simulation to Investigate Magnetic and Wave-Absorbing Properties of Iron Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chuan-Wen%20Liu">Chuan-Wen Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Min-Hsien%20Liu"> Min-Hsien Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung-Chieh%20Tai"> Chung-Chieh Tai</a>, <a href="https://publications.waset.org/abstracts/search?q=Bing-Cheng%20Kuo"> Bing-Cheng Kuo</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheng-Lung%20Chen"> Cheng-Lung Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Huazhen%20Shen"> Huazhen Shen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A recent surge in research on magnetic radar absorbing materials (RAMs) has presented researchers with new opportunities and challenges. This study was performed to gain a better understanding of the wave-absorbing phenomenon of magnetic RAMs. First, we hypothesized that the absorbing phenomenon is dependent on the particle shape. Using the Material Studio program and the micro-dot magnetic dipoles (MDMD) method, we obtained results from magnetic RAMs to support this hypothesis. The total MDMD energy of disk-like iron particles was greater than that of spherical iron particles. In addition, the particulate aggregation phenomenon decreases the wave-absorbance, according to both experiments and computational data. To conclude, this study may be of importance in terms of explaining the wave- absorbing characteristic of magnetic RAMs. Combining molecular dynamics simulation results and the theory of magnetization of magnetic dots, we investigated the magnetic properties of iron materials with different particle shapes and degrees of aggregation under external magnetic fields. The MDMD of the materials under magnetic fields of various strengths were simulated. Our results suggested that disk-like iron particles had a better magnetization than spherical iron particles. This result could be correlated with the magnetic wave- absorbing property of iron material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wave-absorbing%20property" title="wave-absorbing property">wave-absorbing property</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20material" title=" magnetic material"> magnetic material</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-dot%20magnetic%20dipole" title=" micro-dot magnetic dipole"> micro-dot magnetic dipole</a>, <a href="https://publications.waset.org/abstracts/search?q=particulate%20aggregation" title=" particulate aggregation"> particulate aggregation</a> </p> <a href="https://publications.waset.org/abstracts/78242/computer-simulation-to-investigate-magnetic-and-wave-absorbing-properties-of-iron-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78242.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">490</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1390</span> Effect of Al Contents on Magnetic Domains of {100} Grains in Electrical Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyunseo%20Choi">Hyunseo Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaewan%20Hong"> Jaewan Hong</a>, <a href="https://publications.waset.org/abstracts/search?q=Seil%20Lee"> Seil Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Mo%20Koo"> Yang Mo Koo </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non-oriented (NO) electrical steel is one of the most important soft magnetic materials for rotating machines. Si has usually been added to electrical steels to reduce eddy current loss by increasing the electrical resistivity. Si content more than 3.5 wt% causes cracks during cold rolling due to increase of brittleness. Al also increases the electrical resistivity of the materials as much as Si. In addition, cold workability of Fe-Al is better than Fe-Si, so that Al can be added up to 6.0 wt%. However, the effect of Al contents on magnetic properties of electrical steels has not been studied in detail. Magnetic domains of {100} grains in electrical steels, ranging from 1.85 to 6.54 wt% Al, were observed by magneto-optic Kerr microscopy. Furthermore, the correlation of magnetic domains with magnetic properties was investigated. As Al contents increased, the magnetic domain size of {100} grains decreased due to lowered domain wall energy. Reorganization of magnetic domain structure became more complex as domain size decreased. Therefore, the addition of Al to electrical steel caused hysteresis loss to increase. Anomalous loss decreased and saturated after 4.68% Al. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20steel" title="electrical steel">electrical steel</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20domain%20structure" title=" magnetic domain structure"> magnetic domain structure</a>, <a href="https://publications.waset.org/abstracts/search?q=Al%20addition" title=" Al addition"> Al addition</a>, <a href="https://publications.waset.org/abstracts/search?q=core%20loss" title=" core loss"> core loss</a>, <a href="https://publications.waset.org/abstracts/search?q=rearrangement%20of%20domains" title=" rearrangement of domains"> rearrangement of domains</a> </p> <a href="https://publications.waset.org/abstracts/74890/effect-of-al-contents-on-magnetic-domains-of-100-grains-in-electrical-steels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74890.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1389</span> Effects of Magnetic Field Strength on Fluid Flow Behavior in a Constricted Channel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashkan%20Javadzadegan">Ashkan Javadzadegan</a>, <a href="https://publications.waset.org/abstracts/search?q=Aitak%20Javadzadegan"> Aitak Javadzadegan</a>, <a href="https://publications.waset.org/abstracts/search?q=Babak%20Fakhim"> Babak Fakhim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of possible ways to retard movement of fluid is through applying an external magnetic field.

Also, Ellis Non-Newtonian model is implemented to address the effects of shear-dependent viscosity. According to the results, the flow separation downstream of the constriction can be controlled by applying an external magnetic field and/or manipulating the shear-thinning degree of fluid. It is also demonstrated that pressure drop increases by an increase in the strength of the magnetic field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title="magnetic field">magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=non-Newtonian" title=" non-Newtonian"> non-Newtonian</a>, <a href="https://publications.waset.org/abstracts/search?q=separation" title=" separation"> separation</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20thinning" title=" shear thinning"> shear thinning</a> </p> <a href="https://publications.waset.org/abstracts/3080/effects-of-magnetic-field-strength-on-fluid-flow-behavior-in-a-constricted-channel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3080.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">432</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1388</span> Design of Advanced Materials for Alternative Cooling Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emilia%20Olivos">Emilia Olivos</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20Arroyave"> R.

At present researchers focus mainly on environmentally-friendly magnetic materials and the potential application in cooling devices. The magnetic materials presented in this project belong to a group known as Heusler alloys. These compounds are characterized by a strong coupling between their structure and magnetic properties. Usually, a change in one of them can alter the other, which implies changes in other electronic or structural properties, such as, shape magnetic memory response or the magnetocaloric effect. Those properties and its dependence with external fields make these materials interesting, both from a fundamental point of view, as well as on their different possible applications. In this work, first principles and Monte Carlo simulations have been used to calculate exchange couplings and magnetic properties as a function of an applied magnetic field on Heusler alloys. As a result, we found a large dependence of the magnetic susceptibility, entropy and heat capacity, indicating that the magnetic field can be used in experiments to trigger particular magnetic properties in materials, which are necessary to develop solid-state refrigeration devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ferromagnetic%20materials" title="ferromagnetic materials">ferromagnetic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetocaloric%20effect" title=" magnetocaloric effect"> magnetocaloric effect</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20design" title=" materials design"> materials design</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20state%20refrigeration" title=" solid state refrigeration"> solid state refrigeration</a> </p> <a href="https://publications.waset.org/abstracts/108024/design-of-advanced-materials-for-alternative-cooling-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108024.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">215</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1387</span> A Study on the Magnetic and Mechanical Properties of Nd-Fe-B Sintered Magnets According to Sintering Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20H.%20Kim">J.

The sintering temperature changed from 950°C to 1120°C. While remanence and hardness of the magnets increased with increasing sintering temperature, the coercivity first increased, and then decreased. The optimum magnetic and mechanical properties of the magnets were obtained at the sintering temperature of 1050°C. In order to clarify the reason for the variation on magnetic and mechanical properties of the magnets, we systematically analyzed the microstructure. <p class="card-text"><strong>Keywords:</strong> <a
