36. Dynamic microphones are based on which principle?
- Superposition
- Electromagnetic induction
- Electromagnetism
- Wave-particle duality
Answer: B) Electromagnetic induction
Explanation:
Dynamic microphones work on electromagnetic induction. Electromagnetic induction is a phenomenon that occurs when a conductor is subjected to a changing magnetic field and induces an electric current in it. Electromagnetic induction is used by dynamic microphones to transform sound waves into electrical impulses.
