Abstract
An apparatus and process are provided for reducing the electromagnetic field intensity in selected regions for a field produced when ac current flows through one or more induction coils through which a workpiece moves for induction heating of the workpiece. The electromagnetic shield has transverse screen elements through which the workpiece moves at opposing ends of the one or more induction coils. One or two longitudinal screen elements connect the transverse screen elements.
