Feritni magnet je vrsta trajnog magneta uglavnom napravljenog od SrO ili Bao i Fe2O3. To je funkcionalni materijal izrađen keramičkim postupkom, sa širokom histerezisnom petljom, visokom koercitivnošću i velikom remanentnošću. Jednom magnetiziran, može održavati konstantan magnetizam, a gustina uređaja je 4,8 g/cm3. Compared with other permanent magnets, ferrite magnets are hard and brittle with low magnetic energy. However, it is not easy to demagnetize and corrode, the production process is simple and the price is low. Therefore, ferrite magnets have the highest output in the whole magnet industry and are widely used in industrial production.
