This type of magnet is made of bonded ferrite magnet powder, Plastics(pvc,nylon,pp,ect) and other materials, By injecting process, the combination can be made into flexible magnets with precise sizes and complicated shapes which can be inserted in metal and plastic pieces. They are widely used in DC permanent motor,step moter, meter moter, printer and duplicator roller, cushion cylinder, inductor, sensor and kinescope collector,etc.
