ʻO ka Ferrite he mea ʻokikene metala o kahi hui ferrous.Ma ke ʻano o ka uila, ʻoi aku ka nui o ka resistivity o nā ferrites ma mua o nā mea hoʻohui metala metala, a loaʻa pū kekahi mau waiwai o ka dielectric.He haʻahaʻa ka ikehu mākēneki no kēlā me kēia ʻāpana o ka ferrite Ke hōʻiliʻili ʻia ke alapine kiʻekiʻe, haʻahaʻa ka ikehu makeke no kēlā me kēia leo o ka ferrite.(Bs) ka ikaika haʻahaʻa (wale nō 1/3 ~ 1/5 o ka hao maʻemaʻe), e kaupalena ana i ka laulā o nā koho a hoʻopaʻa i ka laulā o nā pono, a hiki ke hoʻohana nui ʻia i nā noi ikaika maʻamau i kēia manawa ma nā kahua like ʻole.
Hoʻopili ʻia ʻo Ferrite mai nā mea hao hao a me nā mea ʻē aʻe.ʻO ka maʻamau, hiki ke hoʻokaʻawale ʻia i ʻekolu ʻano: ferrite mau, ferrite palupalu a me gyromagnetic ferrite.
Ua kapa ʻia ʻo ferrite magnet paʻa, ʻo ia ka magnet ʻeleʻele liʻiliʻi a mākou e ʻike mau ai.ʻO kāna mau mea maka nui he hao hao, barium carbonate a i ʻole strontium carbonate.Ma hope o ka magnetization, kiʻekiʻe loa ka ikaika o ke koena magnetic field, a hiki ke mālama ʻia ke koena magnetic field no ka manawa lōʻihi.Hoʻohana mau ʻia ma ke ʻano he mea magnet mau loa.Laʻana: mākēneki leo leo.
Hoʻomākaukau ʻia ka ferrite palupalu a hoʻopaʻa ʻia e ka ferric oxide a me hoʻokahi a i ʻole kekahi mau mea metala ʻē aʻe (e laʻa: nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, etc.).Ua kapa ʻia ʻo ia ka soft magnetic no ka mea i ka nalo ʻana o ke kahua magnetizing magnetic, ʻaʻohe liʻiliʻi a ʻaʻohe koena mākena magnetic.Hoʻohana maʻamau e like me ka coil choke, a i ʻole ke kumu o kahi transformer alapine waena.He okoa loa keia mai ka ferrite mau.
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 ke ʻano o ka mokulele o ka polarization o kahi mokulele-polarized electromagnetic hawewe e hoʻolaha i kekahi ʻaoʻao i loko o ka mea ma lalo o ka hana o ʻelua mau pā magnetic DC a me nā māla electromagnetic hawewe.Ua hoʻohana nui ʻia ka gyromagnetic ferrite ma ke kahua o ka kamaʻilio microwave.Wahi a ke ʻano aniani, hiki ke hoʻokaʻawale ʻia ka gyromagnetic ferrite i ke ʻano spinel, ʻano garnet a me ke ʻano magnetoplumbite (hexagonal type) ferrite.
Hoʻohana nui ʻia nā mea magnetic a hiki ke hoʻohana ʻia i ka electro-acoustic, telecommunications, mita uila, motors, a me nā ʻāpana hoʻomanaʻo, nā ʻāpana microwave, etc. no nā lolouila, a me nā kāleka makeke no nā palapala hoʻopaʻa kau ʻana a me ka hoʻoholo uku.ʻO kēia ka mea e pili ana i nā mea magnetic i hoʻohana ʻia ma ka tape magnetic a me ke kumu o ka hana.
