Abstract
A device for providing electromagnetic levitating forces and heating is described. A plurality of separate coils are provided, each powered by a separate power amplifier. Each coil may be supplied with two separate frequencies, one to levitate, and the other to heat the object. Also, the coils may be driven at separate phases to more uniformly distribute the magnetic levitating and heating forces.
