- An induction stove works on the principle of electromagnetic induction.
- A metal coil is kept just beneath the cooling surface. It carries alternating current (AC). So that AC produces an alternating magnetic field.
- When you keep a metal pan with water on it, the varying magnetic field beneath it crosses the bottom surface of the pan and EMF is induced in it.
- Since pan has a finite resistance, the flow of induced current in it produces heat in it and this heat is conducted to the water.
- That’s why we call this stove as induction stove.
