A mathematical model is developed to determine the force impacts that are formed when the electromagnetic field is transformed into a field of ultrasonic oscillations in the skin layer of an electrically conductive ferromagnetic material of an anisotropic magnetic permeability. The main factors determining the excited acoustic field with allowance for permissible limitations are established. It is shown that the main contribution to the acoustic vibrations energetics is made by the magnetostrictive component of the skin layer material, in which the high-frequency electromagnetic field is transformed into an acoustic field.
