This presentation concerns a study of micromagnetic simulations incorporating eddy current losses for soft magnetic materials with different conductivities to investigate the conductivity and defect size on the magnetic domain structure and to analyze the magnetic energies. This method enabled a more accurate evaluation of iron loss in soft magnetic materials for high frequency applications and clarified the influence of eddy currents in the total energy on magnetization dynamics.
