Abstract
A latching electromagnetically actuable device comprises an electromagnet and an electrical coil. The electromagnet comprises an armature and a core. At least one of the armature and the core is of a magnetically hard material. A housing supports the electromagnet and the coil. Energizing the coil in a first direction magnetizes the magnetically hard material to draw the armature and core together and latch the electromagnet. Energizing the coil is a second direction releases the electromagnet.
