  • Magnetic actuator drive for actuation and resetting of magnetic actuation materials
    Patent number: 7218067
    Abstract: A magnetic actuator is provided including a magnetic field-actuated material and a plurality of interconnected electrically conducting coils, each coil including a number of wire turns arranged relative to at least one other coil to produce at the magnetic field-actuated material, by superposition, a magnetic field that is substantially oriented in one of a plurality of selectable discrete directions. An actuator drive circuit is connected to the coils in a circuit configuration that reverses a direction of electrical current flow through at least one of the coils to reorient the magnetic field from a first selected direction to a second selected direction of the plurality of selectable discrete directions.
