The element of the induction cooker, as can be learnt from the name, is the induction coil (electromagnet), placed under the ceramic plate. It creates, together with the bottom of the pot, an electromagnetic circuit, which causes only the bottom base of the utensil to be heated by the plate (98% of the electricity is converted into heat). By using the common electrical equipment (electric cooker, common glass–ceramic plate) the heat has to pass through the plate and then it transmits the energy into the utensil, which is used for cooking. Huge energy dissipation is involved in each energy transmission.
