A magnetic dipole experiences a torque of 
when placed in uniform magnetic field in such a way that dipole moment makes angle of 
with magnetic field. The potential energy of the dipole is:
A
B
-80 J
C
80 J
D
-60 J
Text Solution
Verified by ExpertsThe correct answer is:
B
To determine the potential energy of a magnetic dipole in a uniform magnetic field, we start with the torque equation:
Given that 
and 
, we can equate and solve for 
:
Solving for 
, we find:
The potential energy 
of the dipole in the magnetic field is given by:
Substituting in 
, we calculate:
Thus, the potential energy of the dipole is -80 J.
