A magnetic head for a magnetic pick-up tool includes a magnet having a pick-up surface and a sleeve member having an open end and being slidably positioned over the magnet, the sleeve member being made of a material acted upon by the magnet such that the magnet exerts a force upon the sleeve for maintaining the sleeve in a rest position wherein the open end extends beyond the pick-up surface, wherein the sleeve is slidable in a direction away from the pick-up surface and against the force to a withdrawn with respect to the magnet. A magnetic pick-up tool including a magnet head is also disclosed.
