Abstract
A semi-releasable magnetic tool is disclosed. The tool comprises two magnetizable pole plates. Each of said pole plates is bounded by peripheral edges. The pole plates are spaced apart and preferably disposed in substantial registry with one another. A generally non-magnetizable spacer member is positioned between the pole plates and spaced inwardly from the peripheral edges. A magnetic switch is mounted between the pole plates. The switch is switchably associated with at least one magnetic element. The magnetic element positioned so as to magnetize the pole plates. The magnetic element can be switchably moved toward and away from the pole plates so that they are strongly or weakly magnetized. The magnetization of the tool in the weaker configuration is such that the tool can be easily placed in a desired position on a magnetizable workpiece. The tool is clamped in position on the workpiece by moving the magnet(s) closer to the pole plates.
