The cooking zone is covered by a glass ceramic plate under which an induction coil is placed. From an built-in generator with control unit a high frequent alternating current is led through the induction coil, this creates a magnetic field. The electromagnetic waves from the magnetic field penetrate the ceran plate and develop heat in the bottom of the magnetic pot or pan.
As the heat does not have to be transmitted to the bottom of the pan or pot by hot metal- or glass ceramic hob elements, the heat development in the pot or pan happens immediately when the cooking zone is turned on, and likewise the heat development in the pot or pan stops immediately when the cooking zone is turned off. Consequently the pot or pan also reacts immediately on changes in the heat adjustment.
As the ceramic plate is not heated, there is no heat loss or heat emission from the cooking zones, which means high efficiency, improved working conditions, easier cleaning and less need for ventilation and extraction around the cooking range.
