Learn About Induction Heating Work Coils
The work coil is used to transfer the energy from the induction heating power supply and workhead to the work piece by generating an alternating electromagnetic field. The electromagnetic field generates a current that flows in the work piece as a mirror image to the current flowing in the work coil. As the current flows through the resistivity of the workpiece it generates the heat within the work piece from I²R losses.
A second heating principle, hysteretic heating is also in effect when the work piece is a magnetic material such as carbon steel. Energy is generated within the work piece by the alternating magnetic field changing the magnetic polarity within the work piece. Hysteretic heating occurs in the work piece only up to the Curie temperature (750° C for steel) when the material''s magnetic permeability decreases to 1.
