Hoʻohana nui ʻia ma nā wahi ʻelua no ka hoʻololi ʻana i ka ikehu a me ka hana ʻana i ka ʻike

I ka ʻoihana mana, ʻo ke kahua magnetic kiʻekiʻe he kiʻekiʻe ka hoʻokomo magnetic a me ka pohō kumu haʻahaʻa o ka huila. I ka ʻoihana uila, ʻo ke kumu nui ma ka huila haʻahaʻa a waena paha me ka permeability magnetic kiʻekiʻe a me ka ikaika coercive haʻahaʻa. I nā alapine kiʻekiʻe e hana ʻia ma kahi ʻāpana lahilahi a i ʻole ka huila me ka resistivity kiʻekiʻe. ʻO ka maʻamau me ka pepa a i ʻole ka ʻāpana.

ʻO nā mea makeneka palupalu i ka hoʻololi ʻana no ka hoʻohana ʻana, ma muli o nā kahe eddy makeneka ʻē aʻe i hoʻokomo ʻia i loko o ka mea, e hopena ana i ka pohō, ʻo ka liʻiliʻi o ke kūpaʻa o ka alloy, ʻoi aku ka nui o ka mānoanoa, ʻoi aku ke kiʻekiʻe o ke alapine o ke kahua makeneka ʻē aʻe, ʻoi aku ka nui o nā pohō o ke au eddy, ʻoi aku ka nui o ka hoʻemi ʻana o ka makeneka. No kēia, pono e hana ʻia ka mea i kahi pepa lahilahi (tīpine), a uhi ʻia ka ʻili me kahi papa insulating, a i ʻole ka hoʻohana ʻana i kekahi mau ʻano hana i ka ʻili e hana i kahi papa insulating oxide, ʻo ia mau alloys i hoʻohana pinepine ʻia ka uhi electrophoresis magnesium oxide.

Hoʻohana nui ʻia ka hao-nickel alloy i ke kahua magnetic alternating, ʻoiai no ka hao yoke, relay, Small Power Transformers a me ka pale Magnetic.

ʻO ka hana o ka pale magnetic Permalloy: I mea e pale ai i ka hoʻopilikia ʻana o ke kahua magnetic waho, pinepine i ka CRT, kahi ʻāpana e kālele ana i ka kukuna electron CRT waho me ka pale magnetic, hiki iā ʻoe ke pāʻani i ke kuleana o ka pale magnetic.
