    Patent number: 5275514
    Abstract: A portable workpiece-mounted machine tool such as a drill is provided with a permanent-electromagnet attaching unit which has its reversible permanent magnets alternating with nonreversible permanent magnets so that, when electric current is applied to the reversible magnets, they are subjected to polarity reversal which causes flux closure through a workpiece of the reversible and nonreversible magnets in the "on" position and causes flux closure between a reversible and nonreversible magnet in an "off" position.
