    2.3. INDUCTION COOKING OPERATING PRINCIPLE: Induction cooking is based on the physical principle of heating, utilising Foucault current, of electrically conductive materials Foucault current is generated when conductive material is exposed to an AC electromagnetic fi eld. Induction heating exploits the phenomenon of parasitic currents (also known as Foucault currents). Parasitic currents are produced in conductive materials by variable magnetic fl...
