Induction heating mainly uses the principle of electromagnetic induction. When a current passes through a coil to generate an alternating magnetic field, it is repeatedly cut and changed inside an iron pot, a pipe, etc., so that a ring current (eddy current) is generated, so that the iron vessel itself is heated. This kind of vibration heating method can reduce the intermediate part of heat transfer and greatly improve the heating efficiency.
Common applications using electromagnetic induction heating are: induction cooker, electric tea stove, IH rice cooker, industrial heating applications.
