Ni akọkọ lo ni awọn agbegbe meji fun iyipada agbara ati sisẹ alaye

Ninu ile-iṣẹ agbara, nipataki ni aaye oofa giga ni ifakalẹ oofa giga ati isonu mojuto kekere ti alloy. Ninu ile-iṣẹ itanna, nipataki ni kekere tabi alloy alabọde ti o ni agbara oofa giga ati agbara ipasẹ kekere. Ni awọn igbohunsafẹfẹ giga yoo ṣee ṣe lori ṣiṣan tinrin tabi alloy resistivity ti o ga julọ. Nigbagbogbo pẹlu dì tabi rinhoho.

Awọn ohun elo oofa rirọ ni paṣipaarọ fun lilo, nitori alternating magnetic eddy currents is induced in the material, Abajade pipadanu, kere si resistance alloy, ti sisanra ti o tobi, iwọn igbohunsafẹfẹ ti aaye oofa alternating, eddy awọn adanu lọwọlọwọ tobi, oofa dinku diẹ sii. Fun eyi, ohun elo naa gbọdọ jẹ tinrin tinrin (teepu), ati dada ti a bo pẹlu Layer insulating, tabi lilo awọn ọna kan si dada lati ṣe Layer insulating oxide, iru awọn ohun elo ti o wọpọ lo iṣuu magnẹsia oxide electrophoresis.

Iron-nickel alloy okeene ni alternating aaye oofa lilo, o kun fun irin ajaga, yii, Kekere Power Ayirapada ati Magnetically idabobo.

Idabobo oofa oofa Permalloy lati ṣe: Lati ṣe idiwọ kikọlu ti aaye oofa ita, nigbagbogbo ni CRT, apakan idojukọ itanna CRT itanna ita pẹlu apata oofa, o le ṣe ipa ti aabo oofa.
