[0002] Electromagnetic heating is also called electromagnetic induction heating, electromagnetic heating technology, and the principle of electromagnetic heating is that an alternating magnetic field is generated through an electronic circuit board component, when an iron container is placed on the surface, the surface of the container cuts the alternating magnetic force line and generates an alternating current (i.e. eddy current) in the metal part of the bottom of the container. The eddy current makes the carrier particles at the bottom of the container move at high speed in a random manner, and the carrier particles collide and rub with each other to generate heat energy. Thus, the effect of heating the object is achieved. Because the iron container itself generates heat, the heat conversion rate is particularly high, and the highest can reach 95%. It is a direct heating method.
