A current carrying coil having magnetic moment M is placed in a magnetic field B. Initially the magnetic field is perpendicular to the plane of the coil and then coil turned about an axis such that the angle between the magnetic field and the plane of the coil become zero. Then choose the correct statement.
1
The initial torque on the coil was maximum.
2
The final torque on the coil was maximum.
3
Initial potential energy of the coil was zero.
4
All are correct.
