The elements of Ferrite magnet are ferricoxide¡¢barium¡¢strontium.Ferrite
has highter coercive force and highter resistance to bedemagnetized
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... |
