The temperature-dependent relative magnetic permeability depends on the magnetic characteristic of the particular metal parts. This is given a definite value in the current computer simulation of induction heating and is set by the past empirical results. In order to further improve the analytical accuracy of temperature distribution in induction heating simulations, it is necessary to create continual change in the relative magnetic permeability by altering temperature and magnetic field strength. In this study, a computer simulation using the measured data of the B-H curve was applied to the induction heating test of ring specimens. Additionally, the experimental and simulated results were compared in order to examine the validity of this method.
