Material housing: Galvanized steel
Compact magnet systems with a steel shell and a countersunk hole for easy mounting. The bolt with a flat countersunk head falls flush with or in the top of the magnet. This optimizes the attracting surface of the pot magnet. Thanks to the shell of these magnet systems, the magnetic field strength increases and the pot magnets are more resistant to corrosion or chemicals. Pot magnets have a single attracting surface. This precludes dispersion of the magnetic field.Pot magnets with countersunk hole are available in various sizes and types such as neodymium, ferrite and AlNiCo.

Construction of NdFeb pot magnets

What does a neodymium pot magnet consist of?

These super-strong pot magnets are made of the alloy neodymium-iron-boron - (NdFeB) - which Goudsmit markets under the brand name Neoflux®. The shell - or pot - provides magnetic shielding. Goudsmit supplies neodymium pot magnets with a brass or steel shell. The holding surface is covered with a protective coating to prevent corrosion.

Operating temperature

When does loss of magnetic strength occur?

Neodymium pot magnets have a maximum operating temperature of up to 80 °C. When heated to this temperature, the magnet loses 15 to 20% of its magnetic force. This is not permanent; the force is restored when the magnet returns to the normal ambient temperature.
External magnetic fields may also cause loss of magnetic force. An air gap or non-magnetic materials located between the magnet and workpiece reduce the tensile force.
 

Important to know

Tension on the magnet

For pot magnets with a cylinder hole, the magnet has a countersunk hole. Tighten with caution. Excessive tightening causes magnetic splinters or cracks in the magnet.
