Abstract: Magnetic latches and switches based on the flux cancellation or flux diversion principle use the high coercive force of cobaltrare earth permanent magnets such as cobalt-samarium. These permanent magnets are not demagnetized by a flux cancellation coil and can be made thin in the field direction. Devices with thin magnetic circuits and low volume armature achieve high unlatching speeds.
