What Is Induction Cooking? Induction cooking uses electromagnetic fields to heat the pot or pan directly—not the cooktop. Elements beneath the cooking surface produce a magnetic field that causes cookware made of ferrous metals to produce heat. There are two important factors to understand when first using the One Top: The cooktop does not generate heat until you place cookware on the cooking surface.

Use the following guidelines when choosing cookware to use with the One Top: Cookware should be made of cast iron, iron, copper, steel, stainless steel, enameled steel, enameled iron, or aluminum with a steel induction base.

Cookware must fully contact the surface of the cooking element. Induction disks are not recommended. Base of cookware should be 6 to 12 inches in diameter Note: To learn more about induction-compatible cookware, visit Do I need special Cookware to use the One Top?
