A magnetic dipole experiences a torque of $803 N m$ when placed in uniform magnetic field in such a way that dipole moment makes angle of $6 0^{\circ}$ with magnetic field. The potential energy of the dipole is :

Options:

Answer:

Solution:

$τ = M \times B = MB sin 60 = \frac{3}{2} MB = 803$
$MB = 160 U = - M \cdot B = - MB cos 60 U = - 160 \times 1/2 = - 80 J$
