Is there any magnetism in the induction cooker?
No, the energy is produced by electromagnetic coils that radiate to the iron pan to heat the food
The electromagnetic oven is not magnetic, is through the electronic circuit board part produces alternating magnetic field, when the iron pot is placed at the bottom of the furnace surface, the current pan cutting in the bottom of the pot and the alternating magnetic field generated by the alternating metal parts (i.e. eddy current)
The vortex pot iron molecular speed random motion, molecules collide, friction heat (the heat: electromagnetic oven cooking from the bottom of the pot instead of the cooker heating conduction to the pot, so the thermal efficiency than the efficiency of all cooking utensils were nearly 1 times higher than the device itself) high speed heating, for heating and cooking food, so as to achieve the purpose of cooking.
