Pot magnets
Pot magnets have a steel cup for the purpose
of directing the magnetic poles to the same surface.
This increases the magnetic hold significantly compared
with a raw magnet.
In the steel cup there is either a ceramic or a metallic
magnet. The difference between these is mainly in temperature
tolerance; ceramic magnets tolerate ca. 200°C, metallic
magnets ca. 500°C. The ceramic magnets are less
expensive.
Pot magnets usually have some sort of fastening device, a hole or a knob by which they can be fastened onto something. This is what pot magnets are mainly used for. Pot magnets attached with hooks can also be used for hanging things and decorating. A pot magnet with a handle is easy to fasten and unfasten.
