An induction cooker uses a type of induction heating for cooking. A coil of copper wire is placed underneath the cooking pot. An oscillating current is applied to this coil, which produces an oscillating magnetic field. This magnetic field creates heat in two different ways. It induces a current in an electrically conductive pot, which produces Joule (I2R) heat. It also creates magnetic hysteresis losses in a ferromagnetic pot. The first effect dominates; hysteresis losses typically account for less than ten percent of the total heat generated.
Induction cookers are faster and more energy-efficient than traditional cooktops. Unlike traditional cooktops, the pot itself is heated to the desired temperature rather than heating the stovetop, reducing the possibility of injury. Skin can be burned if it comes into contact with the pot, or by the stovetop after a pot is removed. Unlike a traditional cooktop, the maximum temperature in the system is that of the pot, which is much less capable of causing serious injury than the high temperatures of flames or red-hot electric heating elements. The induction cooker does not warm the air around it, resulting in added energy efficiency.
