ʻO Ferrite kahi oxide metala o kahi hui hao. Ma ke ʻano o ka uila, ʻoi aku ka nui o ke kū'ē ʻana o nā ferrites ma mua o nā hui hui hao elemental, a he mau waiwai dielectric nō hoʻi. Haʻahaʻa ka ikehu magnetic no kēlā me kēia anakahi leo o ka ferrite. Ke hōʻiliʻili ʻia ke alapine kiʻekiʻe, haʻahaʻa ka ikehu magnetic no kēlā me kēia anakahi leo o ka ferrite. Haʻahaʻa nō hoʻi ka ikaika o (Bs) (1/3 ~ 1/5 wale nō o ka hao maʻemaʻe), kahi e kaupalena ai i ka laulā o nā koho a kaupalena i ka laulā o nā pono, a hiki ke hoʻohana nui ʻia i nā noi ikaika maʻamau i nā ʻano like ʻole.
Ua sintered ʻia ʻo Ferrite mai nā oxides hao a me nā mea hoʻohui ʻē aʻe. Ma keʻano laulā, hiki ke hoʻokaʻawale ʻia i ʻekolu ʻano: ferrite mau loa, ferrite palupalu a me ka ferrite gyromagnetic.
Ua kapa ʻia hoʻi ʻo ferrite magnet paʻa he magnet ferrite, ʻo ia ka magnet ʻeleʻele liʻiliʻi a mākou e ʻike pinepine ai. ʻO kāna mau mea maka nui he hao oxide, barium carbonate a i ʻole strontium carbonate. Ma hope o ka magnetization, kiʻekiʻe loa ka ikaika o ke kahua magnetic koena, a hiki ke mālama ʻia ke kahua magnetic koena no ka manawa lōʻihi. Hoʻohana pinepine ʻia ma ke ʻano he mea magnet paʻa. Laʻana: nā magnet leo.
Hoʻomākaukau ʻia a hoʻoheheʻe ʻia ka ferrite palupalu e ka ferric oxide a me kekahi a i ʻole kekahi mau oxide metala ʻē aʻe (no ka laʻana: nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, etc.). Ua kapa ʻia ʻo ia he magnetic palupalu no ka mea i ka wā e nalowale ai ke kahua magnetic magnetizing, ʻaʻohe kahua magnetic koena a liʻiliʻi paha. Hoʻohana pinepine ʻia ma ke ʻano he coil choke, a i ʻole ke kumu o kahi mea hoʻololi alapine waena. He ʻokoʻa loa kēia mai ka ferrite mau loa.
ʻO ka ferrite Gyromagnetic e pili ana i kahi mea ferrite me nā waiwai gyromagnetic. ʻO ka gyromagnetism o nā mea magnetic e pili ana i ka hanana e pālahalaha ana ka mokulele o ka polarization o kahi nalu electromagnetic polarized plane-polarized i kahi kuhikuhi i loko o ka mea ma lalo o ka hana a ʻelua mau kahua magnetic DC perpendicular a me nā kahua magnetic nalu electromagnetic. Ua hoʻohana nui ʻia ka ferrite Gyromagnetic ma ke kahua o ke kamaʻilio microwave. Wahi a ke ʻano kristal, hiki ke hoʻokaʻawale ʻia ka ferrite gyromagnetic i ke ʻano spinel, ke ʻano garnet a me ke ʻano magnetoplumbite (ʻano hexagonal) ferrite.
Hoʻohana nui ʻia nā mea makeneka a hiki ke hoʻohana ʻia i ka electro-acoustic, nā kelepona, nā mika uila, nā motika, a me nā ʻāpana hoʻomanaʻo, nā ʻāpana microwave, a pēlā aku. Hiki ke hoʻohana ʻia e hoʻopaʻa i nā lipine ʻike ʻōlelo, mele, a me nā kiʻi, nā mea mālama makeneka no nā kamepiula, a me nā kāleka makeneka no nā palapala hoʻopaʻa kau o ka poʻe holo kaʻa a me ka hoʻoponopono uku. Ke nānā nei kēia ma nā mea makeneka i hoʻohana ʻia ma ka lipine makeneka a me ke kumumanaʻo o ka hana.
