Induction Cooking

Induction uses electromagnetic energy to heat cookware made of magnetic material (steel, iron, nickel or various alloys). When the unit is turned on, the coils produce a high frequency alternating magnetic field, which ultimately flows through the cookware. Molecules in the cookware move back and forth rapidly, causing the cookware to become hot and cook the food.

The cooktop's glass-ceramic surface is unaffected by the magnetic field since it contains no magnetic material. The cooktop will remain much cooler to the touch than other cooking surfaces (say, a regular electric or gas range) as it is only warmed from direct contact with the hot pan, not actively heated itself.
