Neodymium pot magnets are made of a powerful Neodymium magnet sunken in to a stainless 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 stainless steel pot increases the adhesive force of the magnets giving them an incredible hold for their size and also increases their resistance to corrosion. An added advantage of pot magnets is that they are resistant to chipping or cracking following constant impact with a steel surface. These magnets are counter-bored on the magnetic face and can be fixed to a surface with a 3mm (0.12 in.) screw, pot magnets are also available with countersinks and threaded studs.
