ABSTRACT OF THE DISCLOSURE The invention provides a method for removal of excess of a liquid metal coating from a substrate, such as a hot dip coated metal substrate, and in preferred embodiments, for control of metal coating thickness. The method involves moving the substrate through a stationary pulsating or alternating magnetic flux. The flux is directed in a path which enters the coating at an entry zone and exits from the coating at an exit zone, those zones being on the external surface of the coating and spaced apart in the direction of advance of the substrate. The frequency and intensity of the flux are controlled so as to exert on the coating surface a force opposing the viscous drag forces exerted in the coating by the moving substrate. Apparatus for use in performing the method is described.
