We have proposed a method of levitating a thin steel plate by moderately bending it beforehand. To elucidate the bending levitation performance, an ultrathin steel plate was levitated; the relationship among the tilt angle of the electromagnets, the standard deviation of the displacement, and the levitation probability was evaluated. Furthermore, to elucidate the effective tilt angle of the electromagnets for bending, the steel plate shape was analyzed using the finite difference method (FDM). When levitating the thin steel plate at the optimal tilt angle of the electromagnets attained by the FDM, a desirable levitation performance was achieved robustly.
