Induction heating occurs when an electromagnetic force field produces an electrical current in a metal part. The alternating current converts to alternating magnetic field through induction coils and then acts on the metal workpieces or graphite. At this time, much closed rotary electric current (eddy) will naturally occur in the workpieces. The current is so strong as short-circuit current. Because current has thermal effect, the workpieces naturally generates much heat due to the resistance to the flow of this electric current. In addition, there is also magnetic hysteresis loss inside the workpieces, which can also make it generate a certain amount of heat. Therefore, the temperature of the workpieces will rapidly rise in a very short time, which can make any metal materials reach the melting point and make graphite sublimate.

What is Induction Heating and How Do Induction Coils Work?
Apr. 22, 2026
Induction heating is a fast, efficient, and non-contact method of heating electrically conductive materials—most commonly metals. It is widely used in industrial processes such as hardening, brazing, forging, and melting because it can deliver precise and localized heat without physical contact or an open flame.

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of induction power supply (induction heater) and inductor (coil) that is a shaped to contour the part, and a work station where the part is held and presented to the coil.
