Annotation	Levitation induction heating represents the first step of levitation melting, which is an advanced technology used for processing of superclean metals or metal alloys. A workpiece is lifted by the Lorentz forces in time variable magnetic field produced by a system of suitably placed field coils and then heated by the Joule losses. The paper deals with optimization of the heating process from the viewpoint of the velocity of heating the workpiece. Investigated is the influence of the its shape (sphere, cylinder, truncated cone) and arrangement of the field coil.
