He aha ka mea maikaʻi loa e hana ai i ka Magnet mau?

Mākēneki mauhe mea nui i nā noi like ʻole, mai nā kaʻa uila a hiki i nā mea mālama magnetic. ʻO ka hoʻomaopopo ʻana i nā mea maikaʻi loa no ka hana ʻana i kēia mau magnet he mea koʻikoʻi ia no ka hoʻomaikaʻi ʻana i kā lākou hana a me ka pono.
ʻO nā mea maʻamau no ka hana ʻana i nā magnet mau loa ʻo neodymium, samarium-cobalt, ferrite, a me alnico. Loaʻa i kēlā me kēia o kēia mau mea waiwai nā mea e kūpono ai no nā noi like ʻole.

Nā Mākēneki Neodymium: Ua kapa pinepine ʻia ʻo NdFeB magnets, hana ʻia nā magnet neodymium mai kahi huila o neodymium, hao, a boron. Ua ʻike ʻia lākou no ko lākou ikaika magnetic ʻokoʻa, e hoʻolilo iā lākou i ke ʻano magnet paʻa ikaika loa i loaʻa. ʻO kā lākou huahana ikehu kiʻekiʻe e hiki ai i nā hoʻolālā liʻiliʻi a maʻalahi i nā noi e like me nā kaʻa a me nā mea hana. Eia nō naʻe, hiki iā lākou ke maʻalahi i ka corrosion, no laila pono pinepine nā pale pale.

Nā Mākēneki Samarium-Cobalt: Hana ʻia kēia mau magnet mai ka hui pū ʻana o ka samarium a me ka cobalt. Uaʻikeʻia lākou no ko lākou kū'ē kiʻekiʻe i ka demagnetization a me ke kūpaʻa wela maikaʻi, e hoʻolilo iā lākou i mea kūpono no nā noi wela kiʻekiʻe. ʻOiai ʻoi aku ka maikaʻi ma mua o nā neodymium magnets, ʻo ko lākou lōʻihi a me ka hana i nā kūlana koʻikoʻi e lilo lākou i koho i koho ʻia i ka aerospace a me nā noi koa.

Mākēneki Ferrite: Iron oxide a me nā mea metala ʻē aʻe, ferrite magnets he kumu kūʻai a hoʻohana nui ʻia i nā huahana mea kūʻai aku. ʻAʻole ikaika lākou ma mua o ka neodymium a me ka samarium-cobalt magnets akā kūpaʻa loa lākou i ka corrosion a hiki ke hana i nā wela kiʻekiʻe. ʻO kā lākou hiki ke hoʻolilo iā lākou i koho kaulana no nā noi e like me nā magnet refrigerator a me nā leo kani.

Alnico Magnets: Hana ʻia mai ka aluminika, nickel, a me ka cobalt, ua ʻike ʻia nā magnet alnico no ko lākou hiki ke kū i nā wela kiʻekiʻe a me ko lākou kūpaʻa magnetic maikaʻi loa. Hoʻohana pinepine ʻia lākou i nā noi e koi ana i kahi kahua magnetic paʻa, e like me nā kīkā uila a me nā mea ʻike.

I ka hopena, ʻo ka mea maikaʻi loa no ka hana ʻana i kahi magnet mau e pili ana i nā koi kikoʻī o ka noi. Hāʻawi ka neodymium magnet i ka ikaika like ʻole, ʻoiai ʻo samarium-cobalt e hāʻawi i ke kūpaʻa kiʻekiʻe. Hana maikaʻi nā ferrite a me alnico magnets i nā noi koʻikoʻi koʻikoʻi, e hōʻike ana i nā ʻano mea like ʻole i loaʻa no ka hana ʻana i nā magnet mau loa.
