Induction cookers

What is Induction:
An Induction-cooker element is a powerful, high-frequency electromagnet, with the electromagnetism generated by sophisticated electronics in the element below the unit's glass surface. When a good-sized piece of magnetic material such as a stainless steel pot is placed in the magnetic field that the element is generating, the field transfers ("induces') energy into that metal. That transferred energy causes the metal (stainless steel pot) to become hot. By controlling the strength of the electromagnetic field, we can control the amount of heat being generated in the cooking vessel and we can change that amount instantaneously.

How Induction Cooking Works:
* The element's electronics power a coil that produces a high-frequency electromagnetic field
* The field penetrates the metal of the cooking vessel and sets up a circulating electric current, which generates
   heat
* The heat generated in the cooking vessel is transferred to the vessel's contents
* Nothing outside the vessel is affected by the field - as soon as the vessel is removed from the element, or the
   element turned off, heat generation stops
