Abstract
A magnet assembly is made up by a plurality of magnet modules each having a permanent magnet adapted to attract a rotatable armature into engagement with the pole pieces of the module. Each module also includes an electromagnetic coil having an axis disposed perpendicular to the pole pieces. When energized, the coil produces flux which causes the permanent magnet flux to bypass the armature and enable release of the armature from the pole pieces.
