ABSTRACT:
An induction heating coil for use in a cooking range or the like. The coil is defined by a flat spiral of electrically conducted wire having at least three radially related sections including a radially outermost section having closely spaced turns, a radially innermost section having closely spaced turns, and a radially intermediate section having widely spaced turns. In one form, the intermediate section turns are uniformly widely spaced. In another form, the intermediate section turns are arranged in widely spaced groups. The disclosed configurations provide a substantially uniform power transfer to the element being heated, such as a ferromagnetic utensil.
