Beschreibung
Zusammenfassung:	Some embodiments provide an apparatus for controlling the motion of a camera component. In some embodiments, the apparatus includes an actuator module. The actuator module includes a plurality of magnets. Each magnet of the plurality of magnets is poled with magnetic domains substantially aligned in the same direction throughout each magnet. The apparatus further includes a coil rigidly disposed around a lens. Each magnet of the plurality of magnets contributes to the forces to adjust focus of the lens based on Lorentz forces generated from the coil.
