The working principle of the electric ceramic stove and the early electric stove, electric heater is the same, the use of electric current flowing through the resistance wire when the thermal effect to heat the food, the stove itself heat, and then transferred to the pots and pans. The working principle of the induction cooker is the same as that of the medium-frequency furnace used in industry, the induction cooker itself does not heat, it produces a high-frequency alternating magnetic field above, the iron pots and pans are in this changing magnetic field, it will induce an electric current, which flows in the bottom of the pot, called eddy current, the use of this electric current and the resistance of the bottom of the pot itself to heat, that is to say, the pots and pans on the induction cooker in the heat, the stove does not heat up. In this way, it seems that induction heating is more direct, and electric ceramic stoves will have losses in heat transfer.
