Inductive power transfer is nowadays a widely used technology, e.g. for inductive heating in industrial applications and household appliances like inductions hobs. An inductive heating system usually consists of a coil (transmitter) which is powered by an alternating current and a ferromagnetic material (receiver), for example a pot. The ferromagnetic material is heated by induced eddy currents and hysteresis losses Regarding to energy efficiency and comfort, it is desirable to minimize the parasitic losses which do not contribute to the heating of the cooking good and to homogenize the temperature distribution within the cooking container. As a future basis for the development of novel cooking containers, we use FEM simulations to investigate the influence of the material parameters of the ferromagnetic material on the efficiency and temperature distribution. In addition to the simulations, parts of the results are verified by experimental investigations.
