Health pot is a new type of electric heating material. The electric heating film electronic paste (metal compound) is sprayed on the glass surface at high temperature to form a plane resistor, and silver electrodes are made at both ends. The electricity generates heat to heat the water in the pot.

The principle of induction cooker is electromagnetic induction, that is, alternating current is used to generate an alternating magnetic field with changing direction through the coil, and eddy current will appear inside the conductor in the alternating magnetic field. This is because the eddy current electric field pushes the carriers in the conductor to move, and the Joule thermal effect of the eddy current heats the conductor, thus realizing heating.
