Question

The magnetic moment is NOT associated with

• A. accelerated charge.
• B. charge moving with constant velocity.
• C. stationary charge.
• D. retarded charge.

Hint:

A stationary charge does not produce a magnetic moment, but moving charges or currents do.

Answer 1

The Correct Option is C

Step 1: Understanding magnetic moments.
The magnetic moment is associated with a moving charge or current, and it arises due to the motion of charged particles, either in circular or spiral motion.
Step 2: Conclusion.
Thus, the magnetic moment is not associated with a stationary charge, as it requires motion to generate a magnetic field. Therefore, the correct answer is (C).
