Question
A current carrying loop is placed in a uniform magnetic field in four different orientations, I, II, III and IV, arrange them in the decreasing order of potential energy
III
IIIIV
The correct answer is:
Potential energy, 
Here M = magnetic moment of the loop
angle between M and B
is maximum when 
and minimum when 
So as 
decrease from 
its PE also decreases.
