Abstract
This paper deals with the design, based on the finite element method, of a high-frequency induction coil shape used in an electromagnetic heating device. In the case of gas heating, the center of a pan placed on the device can be effectively heated. In the case of heating with a conventional exciting coil, the heating condition is not uniform. Therefore, we improved the exciting coil shape for uniform heating by means of three-dimensional eddy current analysis under the thin plate approximation and by conducting an experiment.
