Question

The magnetic dipole moment of current loop is independent of

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

Answer 1

Answer: (D)

magnetic field in which it is laying

$\text{Magnetic moment of the current loop is given by:}$ $M=niA$

$\text{Here,}n=\text{Number of turns},i=\text{Current},A=\text{Area}$

$\text{Therefore,}M\text{is independent of B.}$
