[0002] Electromagnetic heating is also called electromagnetic induction heating, that is, electromagnetic heating technology. The principle of electromagnetic heating is to generate an alternating magnetic field through the components of the electronic circuit board. When an iron container is placed on it, the surface of the container cuts the alternating magnetic field lines and generates alternating current (eddy current) in the metal part at the bottom of the container. The eddy current causes the carriers at the bottom of the container to move irregularly at high speed, and the carriers and atoms collide and rub against each other to generate heat energy. This has the effect of heating the object. Because the iron container itself generates heat, the heat conversion rate is particularly high, up to 95%, which is a direct heating method. Induction cookers, induction cookers, and induction heating rice cookers all use electromagnetic heating technology.
