What are Pot Magnets?

pot-magnets-introductionA pot magnet is a permanent magnet encased in a steel shell, which is sometimes called a pot, hence the name ‘pot’ magnet.The steel pot increases the adhesive force of the magnet on direct contact with a thick iron surface. If there is no direct contact with the counterpart, or if the steel plate is thin, painted or rough, you can strain it much less.

The indicated adhesive force was measured perpendicular to the surface to which the magnet should stick. It takes a lot less strength to move the magnet sideways. Therefore, you can strain a pot magnet much less if you use it on a wall as opposed to using it on the ceiling.

Most pot magnets can be heated to a temperature of up to 80°C without losing their magnetization.

We current produce Neodymium Pot magnet in our own factories and the ferrite pot magnets are from other manufacturers.
