In this paper,a set of basic equations for free vibration of ferromagnetic conducting plates ina transverse magnetic field are presented,in which the coupled effects of magnetization and eddy current onthe mechanical behavior of the plate are included.Based on the quantitative analyses on the vibration fre-quency and the values of the critical magnetic field for several supporting conditions of the plate,the effectsof the conductivity,the magnetic permeability,the thickness of the plate and supporting conditions on the vi-bration frequency of the plate and the critical magnetic field are discussed.
