Electric grill high and low gear adjustment switch principle

Electromagnetic induction eddy current heating principle. Electric grill, is a barbecue grilling tool with electric heating, high and low gear adjustment switch principle is the principle of electromagnetic induction eddy current heating, is the use of alternating current through the coil to generate the direction of constant change of the alternating magnetic field, in the alternating magnetic field in the interior of the conductor will appear eddy current.
