Norint išlaikyti sintezės procesą, dalelės iš karštos plazmos turi būti uždarytos centriniame regione, kitaip plazma greitai atvės. Magnetinio uždarymo sintezės prietaisai išnaudoja tai, kad įelektrintos magnetinio lauko dalelės patiria <a href="https://en.wikipedia.org/wiki/Lorentz_force" class="extiw" title="en:Lorentz force">Lorenco jėgą</a> ir eina sraigtiniais keliais išilgai lauko linijų. </p><p>Paprasčiausia magnetinio uždarymo sistema yra <a href="/wiki/Solenoidas" title="Solenoidas">solenoidas</a>. Solenoido plazma pasisuks aplink jo liniją einančias lauko linijas, neleisdama judėti šonų link. Tačiau tai netrukdo judėti link galų. Akivaizdus sprendimas yra sulenkti solenoidą aplink apskritimą, suformuojant torą. Tačiau buvo įrodyta, kad tokia tvarka nėra vienoda; dėl vien tik geometrinių priežasčių lauko išorinis toro kraštas yra mažesnis nei vidiniame krašte. Dėl šios asimetrijos elektronai ir jonai <a href="https://en.wikipedia.org/wiki/Guiding_center" class="extiw" title="en:Guiding center">dreifuoja per lauką</a> ir galiausiai atsitrenkia į toro sienas. </p><p>Išeitis yra suformuoti linijas taip, kad jos ne tik bėgiotų aplink torą, bet ir suktųsi kaip juostelės ant kalėdinio ledinuko.Tokiame lauke bet kuri dalelė atsidurs išoriniame taške, kur ji dreifuos į vieną pusę, tarkime į viršų, sekdama savo magnetinę liniją aplink torą, ji atsidurs vidinėje pusėje, kur nukreips kitą būdu. Šis dalelių tvardymas nėra tobulas tačiau skaičiavimai parodė jog tai yra pakankama norint palaikyti kurą reaktoriuje reikalingą laiko tarpą. </p> <div class="mw-heading mw-heading2"><h2 id="Šaltiniai"><span id=".C5.A0altiniai"></span>Šaltiniai</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Tokamakas&veaction=edit&section=3" title="Redaguoti skyrelį: Šaltiniai" class="mw-editsection-visualeditor"><span>redaguoti</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Tokamakas&action=edit&section=3" title="Edit section's source code: Šaltiniai"><span>redaguoti vikitekstą</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="references-small" style="list-style-type: decimal;"> <ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text"><i><a rel="nofollow" class="external text" href="https://www.vle.lt/Straipsnis/tokamakas-96047">Tokamakas</a></i>. <a href="/wiki/Visuotin%C4%97_lietuvi%C5%B3_enciklopedija" title="Visuotinė lietuvių enciklopedija">Visuotinė lietuvių enciklopedija</a>, T.
