Induction forging - Wikipedia

Process. Induction heating is a non-contact process which uses the principle of electromagnetic induction to produce heat in a workpiece. By placing a conductive material into a strong alternating magnetic field, electric current is made to flow in the material, thereby causing Joule heating.In magnetic materials, further heat is generated below the Curie point due to hysteresis losses.
