What is Pot Magnet?

Pot magnets or cup magnets are named after their shape and they both refer to the same group of magnetic products.  By gluing a round shape magnet into a steel pot/cup you get a prototype pot magnet. Pot magnets, also known as cup magnets or round base magnets, are magnetic assemblies that consist of a permanent magnet encased within a ferromagnetic cup or pot.

The structure of pot magnet forms a special magnetic circuit to concentrate magnetic field on working side to get much stronger holding force than a single magnet. The steel housing also protects brittle magnet materials typically NdFeB and Ferrite from breaking easily.
