Optimizing repulsive lorentz forces for a levitating induction cooker

In this paper we study a novel way of induction cooking. Traditionally, an alternating magnetic field is used to induce currents in a ferromagnetic pan to heat foods. We use non-ferromagnetic materials and optimize the design for high repulsive forces in order to levitate the pan while simultaneously heating it and its contents. Our approach is simulation-based to study the influence of different parameters and to perform multidimensional analyses for high force versus power or loss goals. Finally, an experimental prototype has been realized and successfully operated.
