This paper describes computational analyses and an experiment of thin plate deflection in magnetic field. The authors show the governing equation for the eddy current and the deflection analyses of a thin plate considering the coupling effect between the eddy current and the deflection under non-uniform magnetic field. A computer code considering the effect was developed based on a thin plate approximation. The code was applied to the FELIX cantilevered beam (without torsion) and the results (current density. deflection and bending strain) coincided quite well with the experimental results. The authors performed a plate deflection experiment (with torsion) and the code was also applied to this experiment. The comparison between numerical and experimental results verified the analysis method and the code.
