Abstract
An elongate copper coil with an open center area has a bow-tie shaped non-magnetic metal core disposed adjacent the center of the coil and insulated from the coil. The coil is adapted to be connected to a high frequency alternating current generator for producing a magnetic field in the area surrounding the coil and core for induction heating metal articles such as can ends which are moved continuously past the apparatus. The core changes the pattern of maximum flux density of the magnetic field produced by the coil to facilitate controlled transfer of heat into and out of the can ends.
