Abstract
A variable width transverse flux electric inductor has a fixed powered coil section and associated box-like moveable passive coil sections that electromagnetically couple with magnetic flux generated by current flowing through the fixed powered section. The passive coil sections can be transversely moved across the workpiece to accommodate induction heating of workpieces having different widths or track movement of the workpiece. Alternatively the fixed powered coil section and associated moveable coil sections may be connected to each other through flexible connections, sliding contacts or other means, such as clamps, so that an electrical connection can be maintained between both in any relative position.
