Ferrite Magnet (nke a makwaara dị ka magnetik seramiiki) bụ ndọta na-adịgide adịgide.
Ha na-abụkarị Strontium dabere (SrFe2O3), nke ejiri ihe mgbakwunye Strontium Carbonate rụpụtara iji mee ka arụmọrụ sitere na Barium na-emebi emebi (BaFe2O3).
Ezi ike mmanye ha sitere na anisotropy kristal dị elu nke strontium iron oxide. Otú ọ dị, a pụkwara ịmepụta akụkụ isotropic ebe a chọrọ magnetization multi-pole dị mfe ma dị mfe.
N'ihe gbasara njirimara eletriki, resistivity nke ferrite dị nnọọ ukwuu karịa nke ígwè na ihe magnetik alloy, ọ nwekwara àgwà dielectric dị elu.
Njirimara magnetik nke ferrite na-egosikwa ike dị elu na ugboro dị elu.
Ferrite adịghị eduzi ma nwee nnukwu nguzogide corrosion, acids, salts, and lubricants. Ụdị ndị a na-ahụkarị dị mfe, dị ka diski, ngọngọ, cylinders, mgbanaka, na arcs.
A na-ejikarị magnetik Ferrite na ngwa dị iche iche n'ime ọtụtụ iri afọ gara aga, dị ka igwe okwu, moto, na igwe ọkụ.
