Question

The magnetic field interacts with the

• A. Stationary charge only
• B. Moving charges only
• C. Stationary and moving charges
• D. Neither stationary nor moving charges

Answer 1

The correct option is B

Moving charges only

Explanation for Correct Option

1. To produce a magnetic field, a varying electric field is required, and this can be attained by moving electric charges, not by stationary charges.
2. Also, ampere has already stated, that the magnetic field is produced whenever an electric charge is in motion.

Thus, the magnetic field interacts with the moving charges only.

Hence, the correct option is (B).
