Optimizing Repulsive Lorentz Forces for a Levitating Induction Cooker

Abstract

In this paper, we present 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 nonferromagnetic materials and optimize the design for high repulsive forces in order to levitate the pan while simultaneously heating it and its contents. We use a simulation-based approach to study the influence of different parameters and to perform multidimensional analyses for the high force versus the power or loss goals. Finally, an experimental prototype is realized and successfully operated.
