Kutentha ndi chimodzi mwazinthu zofunika kwambiri zomwe zimapweteka maginito amphamvu, kutentha kumapitiriza kukweza makhalidwe a maginito amphamvu ndi maginito akuyenera kukhala ofooka kwambiri komanso ofooka, zomwe zimatsogolera ku mphamvu ya maginito yamphamvu ndi yofooka, mu kutentha kwakukulu kwa nyengo ya maginito amphamvu ndi kutentha kwambiri kapena kucheperachepera, kutentha kumapweteka maginito ndi mphamvu ya maginito ndi chinthu chofunika kwambiri pa kutentha kwa nthawi yomweyo kuvulaza, luso laukadaulo la zida zamagetsi mkati. maginito amphamvu adzawongolera zida zamagetsi zomwe zimatsogolera ku zida zamagetsi zida zambiri zamagetsi zimatha kuthana ndi mamolekyulu, zomwe zimapangitsa kuti pakhale kuchuluka kwa zida zamagetsi zomwe zili ndizomwe zikuyenda kwambiri kuti zichepetse, motero kulimbikitsa gawo lamphamvu la maginito kuti liwonongeke. .
Popeza maginito amphamvu amakhudzidwa kwambiri ndi kutentha kwa ntchito, kutentha kwakanthawi kochepa kwa malo ndi kutentha kosalekeza kokulirapo kungayambitse magawo osiyanasiyana a demagnetization ya gawo lamagetsi, kuphatikiza kuwoloka ndi kosasinthika, kukonzedwa komanso kosasinthika.
Maginito amphamvu amapaka chinthucho poyikapo, ndipo chifukwa cha mawonekedwe a maginito amphamvu ndi osalimba, zomwe zimapangitsa kuti ziwonongeke komanso zing'onozing'ono.Choncho, maginito amphamvu nawonso adzafowoka pang'onopang'ono.Mofanana ndi magetsi, maginito amphamvu sawoneka ndipo sangathe kumveka, koma pamene thupi lachitsulo lili pafupi ndi magnetism.Maginito amphamvu amatchedwa okhazikika maginito zipangizo, ndi demagnetization si ogwirizana ndi nthawi, koma pali zinthu ziwiri zomwe zimabweretsa demagnetization ya maginito amphamvu: kutentha ndi makutidwe ndi okosijeni, ndi demagnetization zidzachitika kutentha kwambiri kuposa Curie kutentha. pa 300 ℃.
