Portable Induction Burner

How Induction Cooking Works:

Induction is a third method, completely different from all other cooking technologies--
it does not involve generating heat which is then transferred to the cooking vessel,
it makes the cooking vessel itself the original generator of the cooking heat.

1. The element's electronics power a coil that produces a high-frequency electromagnetic field.

2. The field penetrates the metal of the ferrous (magnetic-material) cooking vessel and sets up a circulating electric current, which generates heat. (But see the note below.)

3. The heat generated in the cooking vessel is transferred to the vessel's contents.

4. 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.
