Ferrite bụ ọla oxide nke ihe na-emepụta ihe.N'ihe gbasara ọkụ eletrik, ferrite nwere nnukwu resistivity karịa ihe mejupụtara metal alloy elemental, ma nweekwa akụrụngwa nke dielectric.Ike magnetik kwa otu olu nke ferrite dị ala Mgbe a na-akwakọba ọtụtụ ugboro, ike magnetik kwa otu olu nke ferrite dị ala.(Bs) bụkwa ike dị ala (naanị 1/3 ~ 1/5 nke ígwè dị ọcha), nke na-egbochi oke nhọrọ ma na-egbochi ụdị mkpa dị iche iche, a pụkwara iji ya mee ihe na ngwa ngwa siri ike dị ugbu a na mpaghara dị iche iche.
