Rubber magnet is a composite material made of ferrite magnetic powder mixed with rubber raw materials, which is made into finished products by extrusion or rolling. Due to the high plasticity of the material itself, the finished product or semi-finished product can be cut, punched, longitudinally cut and attached to other materials at will, which is not easy to degauss and has good corrosion resistance. Because of the abundant raw materials, the price is low.

It is mainly divided into two categories: the same-sex rubber magnetism and the opposite-sex rubber magnetism.

Homosexual rubber is weak in magnetism, and is mainly used for refrigerator magnets, printed matter and promotional items.

Anisotropic rubber magnets have high magnetism, so they are widely used in micro motors and magnetic toys.
