Mathematical formulation of the dynamic boundary value problem of the electro-magnetothermoelasticity for the electric conductive nonferromagnetic plate subjected to adiabatic process of deformation by pulse electromagnetic field has been done. Strict and approximate solutions of the model problem under magnetic impact with the finite speed and under of electromagnetic impact have been obtained. Limits of application of polynomial approximation of unknown functions over the thickness of the plate to find the approximation solutions of the considered problems have been studied.
