A circular current loop of magnetic moment M is in an arbitrary orientation in an external magnetic field B. The work done to rotate the loop by 
about an axis perpendicular to its plane is:
A
MB
B
C
D
Zero
Text Solution
Verified by ExpertsThe correct answer is:
D
The rotation of the loop by 
about an axis perpendicular to its plane make no change in the angle made by axis of the loop with the direction of magnetic field, therefore, the work done to rotate the loop is zero.
