Ferrite ndi okusayidi wachitsulo wa aloyi yachitsulo.Pankhani yamagetsi, ma ferrite ali ndi mphamvu yochulukirapo kuposa nyimbo zoyambira zitsulo, komanso amakhala ndi dielectric.Mphamvu ya maginito pa unit voliyumu ya ferrite ndi yotsika Pamene ma frequency apamwamba amasonkhanitsidwa, mphamvu ya maginito pa unit voliyumu ya ferrite imakhala yochepa.(Bs) imakhalanso ndi mphamvu zochepa (zokha 1/3 ~ 1/5 zachitsulo choyera), zomwe zimalepheretsa zosankha zosiyanasiyana ndikuchepetsa zosowa zosiyanasiyana, ndipo zingagwiritsidwe ntchito kwambiri pazochitika zamakono zamakono m'madera osiyanasiyana.
Ferrite amatsukidwa kuchokera ku iron oxides ndi zosakaniza zina.Nthawi zambiri, imatha kugawidwa m'mitundu itatu: ferrite yokhazikika, ferrite yofewa ndi gyromagnetic ferrite.
Ferrite maginito ferrite amatchedwanso ferrite maginito, amene ndi yaing'ono maginito wakuda ife timakonda kuona.Zida zake zazikulu ndi iron oxide, barium carbonate kapena strontium carbonate.Pambuyo pa maginito, mphamvu ya maginito yotsalira ndiyokwera kwambiri, ndipo mphamvu ya maginito yotsalira imatha kusungidwa kwa nthawi yaitali.Nthawi zambiri amagwiritsidwa ntchito ngati maginito okhazikika.Chitsanzo: maginito olankhula.
Ferrite yofewa imakonzedwa ndikuyikidwa ndi ferric oxide ndi chitsulo chimodzi kapena zingapo zachitsulo (mwachitsanzo: nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, etc.).Amatchedwa kuti maginito ofewa chifukwa mphamvu ya maginito yochititsa chidwi ikazimiririka, pamakhala mphamvu ya maginito yotsala yochepa kapena palibe.Nthawi zambiri amagwiritsidwa ntchito ngati koyilo yotsamwitsa, kapena pakatikati pa thiransifoma yapakatikati.Izi ndizosiyana kwambiri ndi ferrite yokhazikika.
Gyromagnetic ferrite imatanthawuza chinthu cha ferrite chokhala ndi gyromagnetic properties.The gyromagnetism wa zinthu maginito amatanthauza chodabwitsa kuti ndege polarization wa ndege polarized maginito maginito yoweyula zimafalikira mbali ina mkati mwa zinthu pansi zochita za awiri perpendicular DC maginito minda ndi electromagnetic yoweyula maginito minda.Gyromagnetic ferrite yakhala ikugwiritsidwa ntchito kwambiri polumikizana ndi ma microwave.Malinga ndi mtundu wa kristalo, gyromagnetic ferrite imatha kugawidwa mumtundu wa spinel, mtundu wa garnet ndi mtundu wa magnetoplumbite (mtundu wa hexagonal) ferrite.
Zipangizo zamaginito zimagwiritsidwa ntchito kwambiri ndipo zingagwiritsidwe ntchito mu electro-acoustic, telecommunication, mamita magetsi, motors, komanso zigawo za kukumbukira, zigawo za microwave, ndi zina zotero. Zingagwiritsidwe ntchito kujambula chinenero, nyimbo, ndi matepi a chidziwitso cha zithunzi, zipangizo zosungirako maginito. zamakompyuta, ndi maginito makadi a ma voucha okwera anthu okwera ndi kubweza ndalama.Zotsatirazi zikuyang'ana pa zipangizo zamaginito zomwe zimagwiritsidwa ntchito pa tepi ya maginito ndi mfundo zogwirira ntchito.
