These large ferrite (Y30BH) pot magnets are chrome plated with a countersunk hole on the magnetic face. Magnetism is concentrated on one face to provide the maximum holding force.
|Magnetic Face:||32mm dia|
|Vertical Pull (Kg):||6.9|
|Slide Resistance (Kg):||1.38|
|Max Temp (degrees C):||180|
|Fixing:||5mm c/s Screw|
Outstanding value for money, these ferrite pot magnets are made of a ferrite 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 a strong 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.
I LIKED THEM SO MUCH I HAVE ASKED MY SON TO GET ME MORE FOR XMAS!
I bought small ferrite pot magnets to stick a towel over the front window of my wife\''s car to keep it free from frost. They were reasonably priced, came next day and worked well.
