NOWADAYS, the heating technology by using electromagnetic field technology is important in engineering and sciences research. The development of heating technology is classified in various types as induction heating and dielectric heating. The induction heating is induced by using the inductive coil which is generated the magnetic field [1]-[3]. Moreover, when the magnetic field is induced, the electric current flows though the load model. So, the generally of the currents are flowed through in skin depth of the load model and the currents generated the heat at the surface of the load model. The heat is dependent on amount of induction current and the equivalent impedance, which is flow through the current path. Furthermore, the heat is transferred to the other regions of the load model by the heat conduction and the heat convection.
