°° Brief introduction
°°

The elements of Ferrite£®Ceramic£©magnet are ferricoxide 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 etc.
