We have proposed a magnetic levitation control system for thin steel and confirmed the realization by the digital control experiment. However, the case in which only the levitation control is applied for the thin plate, it has no horizontal restraining force in the traveling. Then, the electromagnetic actuators are installed in order to control the horizontal position of the levitated thin steel and the electromagnetic attractive control forces of the actuators are given for the faced two edges of the levitated thin steel from horizontal direction. In this paper, consideration under such condition on the vertical vibration characteristic of the steel plate was carried out. Experiments were performed for a rigid steel beam and a rigid aluminum beam in order to examine the change of the vertical vibration characteristic by the effect of the magnetic field for the plate edge. As a result, it was confirmed that the horizontal magnetic field for the plate edge equivalently affected as a vertical linear spring force.
