How Is Induction Used in Cooktops On Electric Ranges?
The Induction Difference Nearly all forms of cooking depend on generating heat directly. Gas ranges and ovens burn natural gas to generate heat, for example, while electric ranges run electric current through a resistor to do the same. Induction cooking is different. In induction cooking, the range does not generate heat. Instead, it causes the pot or pan itself to make its own heat. The Induction Coil In induction cooking, electric current runs through a coil right below the surface of the cooktop. That current is high frequency alternating current or AC–current that continuously and rapidly changes direction. When electric current flows through a coil, it generates a magnetic field. The magnetic field generated by the induction coil switches directions rapidly like the electric current producing it. Cooking with Induction When an iron or steel pan is placed on top of the cooktop, the electric field produces a current inside of it. This current moves very quickly back and forth insid
