|Title:||POLARIZED MAGNETIC ACTUATORS FOR HAPTIC RESPONSE|
A polarized electromagnetic actuator includes a movable armature, a stator, and at least one coil wrapped around the stator. At least one permanent magnet is disposed over the stator. When a current is applied to the at least one coil, the at least one coil is configured to reduce a magnetic flux of at least one permanent magnet in one direction and increase a magnetic flux of at least one permanent magnet in another direction. The movable armature moves in the direction of the increased magnetic flux.
