ABSTRACT:
The invention provides an electromagnetic actuatable device including at least one current carrying winding having electrical terminals for applying voltage thereacross and a ferrymagnetic member configured to provide a closed magnetic flux path for magnetic flux induced by the winding when voltage is applied thereto. The member is at least partly disposed within the winding and has means locatable at least in proximity to the winding for modifying magnetic field intensity therethrough. One of the windings or members is adapted to be immobilized with respect to the other so that upon the application of voltage to the winding the non-immobilized winding or member is movable with respect to the other as a result of the force developed by the induced flux.
