Abstract :
A surface impedance depending on magnetic field and temperature Z s(H, T) is defined. The proposed definition is carried out from 1-D nonlinear step by step solution of magnetodynamic equation for a range of temperatures. The goal of the Zs(H, T) determination is an accurate and rapid modeling for induction heating applications
