Design of a foil-coiled inductor for the heating of steel wires

The main advantage of induction heating over other heating methods resides in its speed and efficiency of heating. In some cases however, practical constraints can make a high efficiency hard to obtain by using classical solenoid inductors. As a consequence, the performance of other inductor geometries should be studied. This paper deals with the design of a foil-coiled inductor as a possible alternative for classical coils.
