The working principle of the induction heating process is a combined recipe of Electromagnetic induction and Joule heating. Induction heating process is the non-contact process of heating an electrically conductive metal by generating eddy currents within the metal, using electromagnetic induction principle.
The primary component common to all electrical heaters is the electrical resistor. When you turn a heater on, the electrical current that is produced heats up the nichrome wire components — better known as the heating coils — in the unit. Electrical energy is turned into heat as the current passes through the resistor.
