Neodymium pot magnets are made of a powerful Neodymium magnet sunken in to a steel shell meaning that the north pole is on the centre of the magnetic face and the south pole is on the outer edge around it. The steel pot increases the adhesive force of the magnets giving them an incredible hold for their size. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. These magnets have an M3 threaded stud on the non-magnetic face; pot magnets are also available with countersinks and counter-bored holes.
