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 . . 铁氧体由氧化铁、钡、锶等元素组成，与其它非稀土磁钢相比，铁氧体的矫顽力和抗腐性都比较好，尤其它的低成本更是其它磁钢所无法比拟的。它被广泛应用于从电机、扬声器到玩具、工艺品等各个领域
