Modelling and Methods for Calculating of Electromagnetic Field in a Conducting Ferromagnetic Layer

Investigated the voltage of the magnetic and electric fields during induction heating of the electrically conductive ferromagnetic layer in a steady-state, time-periodic electromagnetic field. Embedded two-sided methods of the Runge-Kutta type are derived, with the help of which the problem is solved. Numerical calculations showed that the nonlinear relationship between induction and magnetic field strength significantly affects the distribution of the amplitudes of the harmonics of the field strengths.
