</p><p>电感元件有许多种形式，依據外觀與功用的不同，而會有不同的稱呼。以漆包線繞製多圈狀，常作为<a href="/wiki/%E7%94%B5%E7%A3%81%E9%93%81" class="mw-redirect" title="电磁铁">电磁铁</a>使用和<a href="/wiki/%E5%8F%98%E5%8E%8B%E5%99%A8" title="变压器">变压器</a>等中使用的电感也依外觀称為<b>线圈</b>（coil）。用以對高頻提供較大<a href="/wiki/%E7%94%B5%E6%8A%97" title="电抗">电抗</a>，通過直流或低頻的，依功用常稱為扼流圈（choke），又稱<b>抗流圈</b>。常配合<a href="/wiki/%E9%93%81%E7%A3%81%E6%80%A7" title="铁磁性">铁磁性</a>材料，安装在<a href="/wiki/%E5%8F%98%E5%8E%8B%E5%99%A8" title="变压器">变压器</a>、<a href="/wiki/%E7%94%B5%E5%8A%A8%E6%9C%BA" title="电动机">电动机</a>和<a href="/wiki/%E5%8F%91%E7%94%B5%E6%9C%BA"

</p><p>電感器一詞，通常只用來稱呼以自感或其效應為主要工作情況的元件。非以自感為主的，習慣上大多稱呼它的其他名稱，平常不以電感器稱呼，例如：<a href="/wiki/%E8%AE%8A%E5%A3%93%E5%99%A8" class="mw-redirect" title="變壓器">變壓器</a>、馬達裡的電磁線圈繞組等。 </p><p>在中文裡，電感器一詞在口語上也會被簡稱為電感，但如需嚴謹表達為實體物件的情況，仍宜稱為電感器。 </p> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Electronic_component_inductors.jpg" class="mw-file-description"><img

</p><p>比如，当电流以1安培/秒的变化速率穿过一个1亨利的电感元件，则引起1伏特的感应电动势。当缠绕导体的导线匝数增多，导体的电感也会变大，不仅匝数，每匝（环路）面积，连缠绕材料都会影响电感大小。此外，用高渗透性材料缠绕导体也会令磁通量增加。 </p><p>电感元件即利用这种感应的原理，在电路中发挥了许多作用。 </p> <div class="mw-heading

<p>使用鐵磁性材料而其他部份不變的話，電感會上升，因此品质因数會被提高。但是若頻率上升時，鐵磁性材料的電感會降低，也就是電感是頻率的變數。所以於<a href="/wiki/%E7%94%9A%E9%AB%98%E9%A0%BB" title="甚高頻">甚高頻</a>（VHF）或更高頻的情況下，會傾向使用空氣核心。使用鐵磁性核心的電感元件可能會於大量電流流入時進入<a
