Abstract
There is provided an electromagnetic actuator which includes a coil disposed about a tube bearing a movable armature, the coil being electrically connectable to a circuit configured to provide a current to the coil to generate a magnetic field and magnetic flux in at least one direction. The movable armature is magnetically coupleable with the coil. A flux adjustment element is also provide and is configured for movement within a magnetic flux output by the coil so as to increase a magnetic flux input to the armature upon movement of the flux adjustment element in a first direction and to decrease a magnetic flux input to the armature upon movement of the flux adjustment element in a second direction, wherein the flux adjustment element is externally disposed about a distal end of the tube.
