Utilization of induction heating (IH) cooker is spreading as a normal utensil because it has high efficiency electrically and is easy to treat. Researches to make efficiency higher are continued for the IH cooker. One factor of losses is a leakage flux on the plate of the IH cooker. We had proposed a new coil configuration which has divided coil instead of conventional one coil. And it was reported that higher efficiency was obtained by energizing the inside coil for small pan and the both coils for large pan. In this paper, Finite Element Method (FEM) simulation and experimental is performed to clarify detailed leakage magnetic flux distribution of the divided heating coil. The simulation results are compared with experimental one for conditions of small pan heating and large pan heating, good correspondence between them is obtained. This FEM simulation will be useful for study to get higher efficiency in IH cooker.
