Claim:
1. A magnetic clamping device for magnetically clamping to a magnetically attracted material, comprising: at least one permanent clamping magnet for magnetically clamping to the magnetically attracted material, the magnet being movable relative to the magnetically attracted material from a position remote from the magnetically attracted material to a clamping position for the clamping of the material by the magnet; damping means for damping the movement of the clamping magnet to the clamping position, the damping means biasing the clamping magnet away from the magnetically attracted material to assist release of the clamping magnet from the magnetically attracted material; and support means to which the clamping magnet is mounted for said relative movement of the clamping magnet from the remote position to the clamping position and for withdrawing the clamping magnet relative to the magnetically attracted material to release the magnetically attracted material, wherein the damping means comprises repelling magnets arranged for being moved relative to one another into a magnetically repelling relationship with each other to dampen the movement of the clamping magnet into the clamping position.
