Rubber Magnet
Rubber magnets are molded by mixing rubber with ferrite powder.
The absorption power is substantially weaker than anisotropic ferrite magnets, but machining can be performed easily after purchasing these products, as they can be cut with a pair of scissors or cutters.
The rubber magnets are in wide use all around us, for stationery, DIY arts and crafts as well as manufacturing industry products by taking advantage of their characteristics.
