INDUCTION COOKER:PRINCIPLES OF OPERATION

What is Induction Cooking?   Induction cooking uses induction heating to directly heat a cooking vessel, as opposed to using heat transfer from electrical coils or burning gas as with a traditional cooking stove. To be used on an induction cooktop, a cooking vessel must be made of a ferromagnetic metal, or placed on an interface disk which enables non-induction cookware to be used on induction surface. In an induction cooker, a coil of copper wire is placed underneath the cooking pot. An alternating electric current flows through the coil, which produces an oscillating magnetic field. This field induces an electric current in the pot. Current flowing in the metal pot produces resistive heating which heats the food. While the current is large, it is produced by a low voltage. continue.. Advantage and Disadvantages of Induction Cooker   To serious cooks, the most important favorable point about induction cookers--given that they are as or more "powerful" at heating
