Rubber magnets are made of bonded ferrite magnet powder, compound rubber and other materials. By extruding, rolling or injecting, the combination can be made into soft, plastic and flexible magnets with different shapes such as trip, coil, sheet, and other complicated shapes. They are widely used in micro motor, fridge, disinfecting cupboard, toy, stationery, and ad. etc.
