The flight mechanism that gains thrust by rotating magnetic wings in an alternating magnetic field is proposed. Through the analysis and the experiments with large-sized models whose wing length is from 3 mm to 8.6 mm, some hints for the design of micro-sized models whose wing length is around 1 mm were shown. That is, the wings should be flat, the angle of attack should be over 25 degrees, and the take-off frequency is estimated to be 600 Hz. We made micro-sized models using MEMS technology. The wings are made of electroplated nickel, and a thin glass rod is attached to the center as an axis of rotation. The glass rod is inserted into a small glass tube which works as an outer bearing. The 900 μm long micro-wings succeed in flying up at a rotating frequency of 570 Hz. The thrust generated by the wings at 570 Hz can be regarded as the weight of the micro-wings.
