Electromagnetic heater is the most widely used heating method in industrial field and civil equipment. It adopts electromagnetic heating technology. Electromagnetic induction heating technology is abbreviated as IH (induction heating) technology. It is developed on the basis of Faraday's induction law and is an application form of Faraday's induction law.
Its essence（electromagnetic heater) is to use electromagnetic induction to generate eddy current in the column to heat the workpiece. It converts electric energy into electromagnetic energy, and then electromagnetic energy into electric energy. Electric energy is transformed into heat energy inside the metal, so as to achieve the purpose of heating the metal, so as to eliminate the harm and interference of open fire in the heating process. It is a heating scheme advocated by the state for environmental protection.
