A circular current loop of magnetic moment 
is in an arbitrary orientation in an external uniform magnetic ficld 
. The work done to rotate the loop by 
about an axis perpendicular to its plane is
A
B
C
Zero
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Rotation of loop by 
about an axis perpendicular to its plane does not change the angle between magnetic moment and magnetic field. Hence, no work is done.
