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.
Abstract translation: 基于磁通消除或磁通分流原理的磁锁和开关使用钴 - 钐等钴 - 稀土永磁体的高矫顽力。 这些永磁体不被磁通消除线圈消磁，并且可以在磁场方向上变薄。 具有薄磁路和低体积电枢的器件实现高解锁速度。
