An electromagnetic actuator is disclosed comprising a substantially planar, permanent magnet arrangement providing at least one magnetic field extending generally normal to the plane of the magnet arrangement. Included is at least one conductor extending in a conductor plane generally parallel to the plane of the magnet arrangement with a portion of the conductor in intersecting relation to the field, whereby relative motion is effected between the conductor and the magnetic arrangement in their respective planes upon energization of the conductor. In one embodiment the magnetic arrangement is mounted for movement in a multiplicity of directions in the plane of the magnet arrangement and there are a plurality of separately energizeable conductors lying in or close to the conductor plane, each of the conductors having a portion configured for intersecting the one magnetic field at an angle different from other conductors. |
