Question

Induction stove works on the main principle of \dots

• A. Magnetic induction
• B. Electrostatic induction
• C. Electromagnetic induction
• D. None

Hint:

Induction stoves heat the vessel directly instead of heating the stove surface first, making them faster and more energy efficient.

Answer 1

The Correct Option is C

Concept: Electromagnetic induction is the process in which a changing magnetic field produces induced current in a conductor.

Step 1: Understand the working of an induction stove. An induction stove contains a coil of wire beneath its surface. When alternating current flows through the coil, a continuously changing magnetic field is produced.

Step 2: Formation of induced current. When a metallic utensil is placed on the stove, the changing magnetic field induces eddy currents in the base of the utensil. These currents generate heat due to electrical resistance.

Step 3: Identify the principle involved. Since heating occurs because of induced current produced by changing magnetic field, the stove works on: \[ \boxed{\text{Electromagnetic induction}} \] Hence, the correct answer is option (3).
