Ferrite magnet bụ ụdị magnet na-adịgide adịgide emebere nke SrO ma ọ bụ Bao na Fe2O3. Ọ bụ ihe na-arụ ọrụ nke usoro seramiiki mere, nke nwere nnukwu hysteresis loop, nnukwu mmanye na nnukwu remanence. Ozugbo magnetized, ọ nwere ike ịnọgide na-enwe magnetism mgbe niile, na njupụta ngwaọrụ bụ 4.8g/cm3. E jiri ya tụnyere ihe ndọta ndị ọzọ na-adịgide adịgide, ihe ndọta ferrite siri ike ma na-agbajite na ike magnetik dị ala. Otú ọ dị, ọ dịghị mfe demagnetize na corrode, mmepụta usoro dị mfe na price dị ala. Ya mere, magnetik ferrite nwere mmepụta kachasị elu na ụlọ ọrụ magnet dum ma na-ejikarị eme ihe na mmepụta mmepụta ihe.

Ọ dabara adaba maka nhazi sekit magnetik n'okpuru ọnọdụ ọrụ siri ike. Ihe ahụ siri ike ma na-agbaji agbaji, a pụkwara iji ya mee ihe maka ịkpụ na ngwa emery. Isi akụrụngwa bụ oxide, ya mere ọ dịghị mfe imebi. Ọnọdụ okpomọkụ na-arụ ọrụ: - 40 ℃ ruo + 200 ℃.
A na-ekewa magnetik Ferrite n'ime anisotropy dị iche iche (anisotropy) na isotropy (isotropy). Ihe ndọta Isotropic sintered ferrite na-adịgide adịgide nwere ihe ndọta na-adịghị ike, mana enwere ike ịmegharị ya n'akụkụ dị iche iche nke magnet; Ihe ndọta na-adịgide adịgide nke anisotropic sintered ferrite nwere ihe ndọta siri ike, mana enwere ike ịmegharị ya naanị n'akụkụ ntụzịaka magnetization a kara aka nke magnet.
