He aha ka ʻokoʻa ma waena o nā magnet isotropic a me anisotropic?

Hemākia ferrite isotropiche mea hoʻokalakupua i loaʻa i nā mea like like ma nā ʻaoʻao a pau.Hoʻokumu pinepine ʻia lākou me ka hoʻohana ʻana i kahi kaʻina kaomi maloʻo a pulu paha, kahi e hana ai i nā māla magnetic i hoʻonohonoho ʻia.ʻO kēia ke ʻano o nā mea magnet isotropic i ʻoi aku ka nāwaliwali o nā māla magnetic i hoʻohālikelike ʻia me nā magnet anisotropic.Eia naʻe, ʻoi aku ka liʻiliʻi o ke kumukūʻai a ʻoi aku ka maʻalahi o ka loaʻa ʻana, no laila kūpono lākou i nā noi liʻiliʻi e like me nā magnet refrigerator a me nā mea pāʻani magnetic.

Ma ka lima ʻē aʻe,nā mākēneki ferrite anisotropiche mau magnet me nā kuhikuhi magnetization makemake.Loaʻa kēia ma ka hoʻohana ʻana i kahi māla magnetic ikaika i ka wā o ke kaʻina hana, kahi e hoʻohālikelike ai i nā domain magnetic i nā kuhikuhi kikoʻī.ʻO ka hopena, ua ʻoi aku ka ikaika o nā māneta anisotropic a ʻoi aku ka maikaʻi no nā noi hana kiʻekiʻe e like me nā kaʻa uila, nā mea ʻike, a me nā mea lapaʻau.

ʻO nā ʻokoʻa nui ma waena o isotropic a me anisotropic magnet ko lākou mau waiwai magnetic a me ka hana hana.Loaʻa i nā mea magnet isotropic kahi māla magnetic random a ʻoi aku ka ikaika, ʻoiai ʻo nā magnet anisotropic kahi kuhikuhi makemake o ka magnetization a ʻoi aku ka ikaika.Hoʻohui ʻia, ʻoi aku ka maʻamau o nā magnet anisotropic a makemake paha i nā ʻenehana hana kūikawā.

I ka hōʻuluʻulu ʻana, aia ka ʻokoʻa ma waena o nā magnet isotropic a me nā magnet anisotropic i kā lākou mau waiwai magnetic a me nā noi.Loaʻa i nā mea magnet isotropic kahi māla magnetic random a ʻoi aku ka ikaika, e kūpono ana ia no nā noi maʻalahi.ʻO nā magnet anisotropic, ma ka ʻaoʻao ʻē aʻe, ua makemake lākou i nā kuhikuhi magnetization a ʻoi aku ka ikaika, e kūpono ana iā lākou no nā noi kiʻekiʻe.He mea koʻikoʻi ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o kēia mau ʻano magnet i ke koho ʻana i ka magnet kūpono no kahi noi kikoʻī.
