INDUCTION INDUCTION COOKING HOW INDUCTION COOKING WORKS An induction coil is beneath the ceramic glass cooking surface. This generates magnetic fields, which act directly on the base of the pots and pans as compared to methods that first heat the ceramic glass. This means that the base of the pan is immediately heated up, saving time and energy. Since the heat required for cooking is generated directly in the base of the pan, the Cooking Zone itself warms up only slightly. The cooktop becomes ho

CAUTION: The pan base of suitable kitchenware heats up within a few seconds! Water should boil rapidly. • You can also check cookware suitability with a magnet. If the magnet remains fixed to the base of the pan, the pan is suitable for induction cooking.
