Abstract
An actuator system comprises a magnetomechanical cantilever beam adapted to be responsive to magnetic fields of various magnitudes. The system provides precise and rapid repositioning of the free end of the beam corresponding to the magnitude of the applied magnetic field. The beam is comprised of magnetostrictive ferromagnetic amorphous material and provides efficient, high force, high speed actuation to devices requiring electronically controlled variable displacement motion.
