The current, generated in the workplace as a result of induced voltage depends upon a number of factors. The electrical conductivity of the workplace must be considered. It should be a fairly good electrical conductor in order for the beating effect to be appreciable.nThe shape and length of path which the current must follow to make a complete circuit is of equal importance. The heating will, in general, be most efficient if the work is of such a shape that the current can flow in circular paths.
