A magnetic compass will be deflected if it is kept near a:
Correct answer: B. Charge in motion
- A. Charge at rest
- B. Charge in motion
- C. Positive charge at rest
- D. None of them
Explanation
A magnetic compass will be deflected if it is kept near a charge in motion. Electric charges in motion constitute an electric current, which generates a magnetic field according to Ampère's law. This magnetic field can deflect the needle of a magnetic compass. Electric charges at rest do not generate a magnetic field that can interact significantly with a magnetic compass. Therefore, the correct answer is Charge in motion.

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
