Ceramic
Ceramic pot magnets are also fitted with a steel pot to protect the magnetic field. They require very little building-in height and therefore offer many structural advantages.
Ceramic pot magnets can be used at temperatures of up to 200șC. Heating to this temperature does, however, cause a decrease in magnetic force of approximately 30 to 40%. This is restored when the magnet returns to the normal ambient temperature.

The holding forces have been determined on a polished plate of S235JR (acc. EN1025) with a thickness of 10 mm by pulling the magnet vertically from the surface (1 kg~10N). A variation of -10% of the given values is possible by exception influence holding forces.
Generally, the value will be exceeded. Small cracks in the magnet do not have any affect on the magnetic force.
