Computer modeling for the design of inductors for different applications in the induction heating process often seems to be necessary to save costs caused by the trial and error. In this paper, the effects of the number of loops in the induction heating process with the numerical solution of the Maxwell equations have been investigated using finite element method (FEM) and the COMSOL MULTIPHYSICS software package in three dimensions. Therefore, considering the effect of the number of coil turns on the amount and pattern of heat produced in the workpiece for special applications in the industry and technology is critical. This is because the number of coil turns is one of the important parameters in the design of induction heating systems. At first, a single turn coil is simulated in a three-dimensional model; then multi-turn coils with the turns number 2, 3, and 4 have been considered. The voltage of 200 V with the frequency of 1 KHz has been used, as applied to the coil, to serve as the source of electromagnetic fields. The results of numerical calculations show that the number of coil turns can have a significant effect on quantities such as distribution and intensity of magnetic flux density, eddy currents density in the workpiece, and the volume of heat produced in the coil and workpiece.
