In this paper, influence of coil steps on the induction heating process has been computed using the Finite Element Method (FEM). At first, a single-turn coil with axisymmetric (no step) has been considered, and then the coils with 3, 5 and 7 cm steps have been employed. Voltage 200 volt with frequent of 1 KHz has been used, which it applied to the coil, as source of electromagnetic fields. The results of the calculations show that distribution and intensity of electromagnetic fields, eddy currents in the workpiece, and generated volume heat in the coil and workpiece for the coil without step have a significant difference with other coils (i.e. the coils with steps of 3, 5, and 7 cm).
