Question

The dipole moment of a current loop is independent of

• A. current in the loop
• B. number of turns
• C. area of the loop
• D. magnetic field in which it is situated

Answer 1

The correct option is D magnetic field in which it is situated

Dipole moment of a current loop
$M=N\times i\times A$
So, it is dependent on current in the loop, number of turns and area of the loop.
It is independent of magnetic field in which it is situated.
