Measurements:

These magnets also come in rubber coating in order to provide that extra friction to minimize the slipping across the clamped surface. To offer reduced slip, these magnets have secured vertical surface with a clamp. For note, the pull force values, based upon the Pot Magnet working at maximum magnetic specification clamping onto a much bigger high magnetic permeability mild steel base and the force stated is that required to guarantee removing the Pot Magnet on every occasion.
