Abstract
An electromagnetic actuator having an actuating permanent magnet and a simplified construction is provided. The electromagnetic actuator includes a housing having a base, a side wall extending from the base to a termination plane, and a substantially open side. The electromagnetic actuator further includes a pole piece arranged within the housing, a wire coil positioned around the pole piece and arranged within the housing, and a permanent magnet coupled to the pole piece by a spring and moveable between a first position and a second position. An actuation position of the permanent magnet between the first position and the second position is proportional to a magnitude of a current applied to the wire coil.
