Induction stove, also known as induction cooker, the first household induction cooker was born in Germany in 1957. 1972, the United States began to produce induction cookers, the early 1980s induction cooker in Europe, America and Japan began to sell.
The principle of the induction cooker is the phenomenon of electromagnetic induction, that is, the use of alternating current through the coil to generate the direction of the alternating magnetic field is constantly changing, in the alternating magnetic field in the conductor will appear inside the vortex current (the reason for Faraday's Law of Electromagnetic Induction), this is the vortex electric field to promote the conductor in the current carrier (the pot of electrons and never iron atoms) due to the movement of the vortex electric current of the joule thermal effect to make the conductor heat up, thus heating.
