Ferrite isimbi oxide ye ferrous alloy.Panyaya yemagetsi, ferrite ine yakakura kwazvo resistivity kupfuura elemental simbi alloy nziyo, uye zvakare ine zvimiro zve dielectric.Iyo magnetic energy per unit volume yeferrite yakaderera Kana iyo yakawanda yakawanda yakaunganidzwa, simba remagnetic per unit volume yeferrite yakaderera.(Bs) zvakare yakaderera-simba (chete 1/3 ~ 1/5 yesimbi yakachena), iyo inogadzirisa huwandu hwezvisarudzo uye inodzikamisa huwandu hwakawanda hwezvido, uye inogona kushandiswa zvakanyanya mune yakajairika yakasimba ikozvino maapplication munzvimbo dzakasiyana.
Ferrite inocheneswa kubva kune iron oxides uye zvimwe zvinongedzo.Kazhinji, inogona kukamurwa kuita marudzi matatu: ferrite yechigarire, nyoro ferrite uye gyromagnetic ferrite.
Permanent magineti ferrite inonziwo ferrite magineti, inova idiki magineti dema yatinowanzo kuona.Zvishandiso zvayo zvakakosha ndeye iron oxide, barium carbonate kana strontium carbonate.Mushure memagnetization, simba reiyo yakasara magineti yakakwira zvakanyanya, uye yakasara yemagineti inogona kuchengetedzwa kwenguva yakareba.Inowanzo shandiswa sechigarire magineti zvinhu.Muenzaniso: magineti emukurukuri.
Ferite yakapfava inogadzirwa uye kunyudzwa neferric oxide uye imwe kana akati wandei mamwe simbi oxides (semuenzaniso: nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, nezvimwewo).Inonzi yakapfava magineti nekuti kana iyo magnetizing field inonyangarika, pane zvishoma kana kusaririra magineti.Inowanzo shandiswa seyakadzipwa coil, kana musimboti wepakati frequency transformer.Izvi zvakasiyana zvachose nekusingaperi ferrite.
Gyromagnetic ferrite inoreva chinhu cheferrite chine gyromagnetic properties.Iyo gyromagnetism yezvinhu zvemagineti inoreva chiitiko chekuti ndege yepolarization yendege-polarized electromagnetic wave inopararira mune imwe nzira mukati mechinhu pasi pekuita kweaviri anoenderana perpendicular DC magineti uye emagetsi wave magineti minda.Gyromagnetic ferrite yakashandiswa zvakanyanya mumunda wekutaurirana microwave.Zvinoenderana nerudzi rwekristaro, gyromagnetic ferrite inogona kukamurwa kuita spinel mhando, garnet mhando uye magnetoplumbite rudzi (hexagonal rudzi) ferrite.
Magnetic zvinhu zvinoshandiswa zvakanyanya uye zvinogona kushandiswa mu electro-acoustic, telecommunication, magetsi metres, motors, pamwe nememory components, microwave components, etc. Inogona kushandiswa kurekodha mutauro, mimhanzi, uye mufananidzo matepi eruzivo, magineti yekuchengetedza zvishandiso. yemakomputa, uye magineti makadhi evanokwira mavhocha uye nekubhadhara mari.Izvi zvinotevera zvinotarisa pane magineti anoshandiswa pane iyo magnetic tape uye musimboti wechiito.
