Ferrite ndi chitsulo chosakanizidwa ndi aloyi ya ferrous. Ponena za magetsi, ma ferrite ali ndi mphamvu yolimba kwambiri kuposa zinthu za elemental metal alloy, komanso ali ndi mphamvu ya dielectric. Mphamvu ya maginito pa unit voliyumu ya ferrite imakhala yotsika. Mphamvu ya maginito pa unit voliyumu ya ferrite ikasonkhanitsidwa, mphamvu ya maginito pa unit voliyumu ya ferrite imakhala yotsika. (Bs) imakhalanso ndi mphamvu yochepa (1/3 ~ 1/5 yokha ya chitsulo choyera), chomwe chimachepetsa zosankha zosiyanasiyana ndikuchepetsa zosowa zosiyanasiyana, ndipo chingagwiritsidwe ntchito kwambiri pakugwiritsa ntchito mphamvu yamagetsi yanthawi zonse m'magawo osiyanasiyana.
Ferrite imapangidwa kuchokera ku iron oxides ndi zosakaniza zina. Kawirikawiri, imatha kugawidwa m'magulu atatu: ferrite yokhazikika, ferrite yofewa ndi gyromagnetic ferrite.
Magineti okhazikika otchedwa ferrite amatchedwanso ferrite magnet, yomwe ndi maginito ang'onoang'ono akuda omwe timawaona nthawi zambiri. Zipangizo zake zazikulu ndi iron oxide, barium carbonate kapena strontium carbonate. Pambuyo pa magineti, mphamvu ya maginito otsala imakhala yayikulu kwambiri, ndipo mphamvu ya maginito yotsala imatha kusungidwa kwa nthawi yayitali. Nthawi zambiri imagwiritsidwa ntchito ngati maginito okhazikika. Chitsanzo: maginito olankhula.
Ferrite yofewa imakonzedwa ndikusungunuka ndi ferric oxide ndi chimodzi kapena zingapo zachitsulo oxides (monga: nickel oxide, zinc oxide, manganese oxide, magnesium oxide, barium oxide, strontium oxide, ndi zina zotero). Imatchedwa soft magnetic chifukwa pamene magnetizing magnetic field itha, pamakhala mphamvu yochepa ya maginito yotsalira. Nthawi zambiri imagwiritsidwa ntchito ngati choke coil, kapena pakati pa transformer yapakati. Izi ndizosiyana kwambiri ndi ferrite yokhazikika.
Gyromagnetic ferrite imatanthauza chinthu cha ferrite chokhala ndi mphamvu ya gyromagnetic. Gyromagnetism ya zinthu zamaginito imatanthauza chochitika chakuti ndege ya polarization ya mafunde a electromagnetic omwe ali ndi polarized plane-polarized imafalikira mbali ina mkati mwa chinthucho mothandizidwa ndi maginito awiri a DC omwe ali perpendicular ndi maginito a electromagnetic wave. Gyromagnetic ferrite yagwiritsidwa ntchito kwambiri pakulankhulana kwa microwave. Malinga ndi mtundu wa kristalo, gyromagnetic ferrite ikhoza kugawidwa m'magulu awiri: spinel type, garnet type ndi magnetoplumbite type (hexagonal type) ferrite.
Zipangizo zamaginito zimagwiritsidwa ntchito kwambiri ndipo zingagwiritsidwe ntchito mu ma electro-acoustic, ma telecommunication, ma electrical meter, ma motors, komanso ma memory components, ma microwave components, ndi zina zotero. Zingagwiritsidwe ntchito kujambula mawu, nyimbo, ndi matepi azidziwitso, zida zosungira maginito zamakompyuta, ndi makadi a maginito a ma voucher okwera ndi ndalama zolipirira. Zotsatirazi zikuyang'ana kwambiri zinthu zamaginito zomwe zimagwiritsidwa ntchito pa tepi yamaginito ndi mfundo yogwirira ntchito.
