How Are Ferrite Magnets Made? Ferrite magnet, also know as a ceramic magnet, is a kind of permanent magnet. Compared with other permanent magnets, ferrite magnets are hard and brittle and have lower magnetic energy. But it is not easy to demagnetize, not easy to be corroded, and low in price. Therefore, ferrite magnets are widely used
