Abstract: The electromagnetic actuator comprises a coil, a magnetic actuator member mounted in the coil, at least one ring of magnetic material placed around the coil, and at least one permanent magnet adjacent to one end of the ring and disposed overlying a portion of the outside surface of the coil, the permanent magnet having a magnetic field that extends in an axial direction of the coil, the magnetic actuator member being slidably mounted in a non-magnetic guide member extending inside the coil, and the ring having an end opposite from the magnet which is spaced apart from the non-magnetic guide member by a non-magnetic gap.
