Power is applied to the workpiece by an induction coil. An alternating current flowing through a coil generates a magnetic field. Placing a workpiece within the coil induces eddy currents (resistance) in the piece. Heat is produced where—and only where—these eddy currents flow. Different converters come with different power outputs and frequencies. Output power, the shape of the induction coil and the characteristics of the work piece determine the heat pattern. The depth of heat penetration into the work piece depends on the frequency: the lower the frequency, the deeper the penetration.
