Hard ferrite magnet (Ceramic magnet, magnetic metal, industrial magnet, magnet and steel, strontium ferrite magnet, barium ferrite magnet)
The elements of Ferrite magnet are ferric oxide/barium, strontium. Ferrite has higher coercive force and higher resistance to be demagnetized and oxidized than other non-rare earth permanent magnets. The biggest advantage of such magnet is their low cost. It is widely used from motors and loudspeakers to toys and craft, industrial holding magnet etc ..
