The magnetic dipole moment of a current loop is independent of

Options

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

Answer

A

Explanation

Current loop acts as a magnetic dipole. Its magnetic moment is given by
`M=NIA`
where N= number of turns, I= current in a loop, A=area of the loop.
From the above relation, we can conclude that magnetic dipole moment of a current loop is independent of magnetic field in which it is lying.
