This paper describes the novel micro actuator using permanent magnet and magnetic fluid. The micro electromechanical actuator without the wire for supplying the energy is driven by the magnetic force produced by the alternating magnetic field. The micro actuator is composed of cylindrical neodymium magnet and kerosene-based magnetic fluid. The alternating magnetic field is generated by using of the Helmholtz coil and the bipolar power source. The actuator is the linearly displacement type actuator. The high-speed video camera system is used to measure the displacement of the actuator. It is found that the frequency of the reciprocating motion corresponds to the input frequency, and the amplitude of reciprocating motion has peak value for the input voltage.
