Which among the following does not involve the principle of electromagnetic induction?
- Electric motor
- Electric generator
- Electric geyser
- Induction stove
The Correct Option is C
Solution and Explanation
Electromagnetic induction is the process of generating electric current using a changing magnetic field.
It is the fundamental principle behind:
- Electric motors (convert electrical energy to mechanical energy using electromagnetic induction)
- Electric generators (generate electricity using electromagnetic induction)
- Induction stoves (use rapidly changing magnetic fields to induce currents in metal vessels)
However, an electric geyser works by converting electrical energy into heat energy using a resistive heating element, and does not involve electromagnetic induction.
The correct option is (C): Electric geyser
