Find the angle through which a magnet is to be rotated from rest position when it is suspended in a magnetic field so that it experiences half of the maximum couple

When a magnet is placed in a uniform magnetic field , it experiences

A bar magnet is suspended in a uniform magnetic field in a position such that it experiences maxiumum torque. The angle through which it must be rotated from this position such that it experiences half of the maximum torque. The angle through which it must be rotated from this positon such that it experiences half of the maxium troque is

One bar magnet is suspended so as to rotate freely in horizontal magnetic field. Then .....

A bar magnet of magnetic moment 2.0 A m^(2) is free to rotate about a vertical axis passing through its centre, the magnet is released from rest from east-west position. Then, the kinetic energy of the magnet as it takes north-south position is (horizontal component of earth field is 25 mu T)

A certain proton moving through a magnetic field region experience maximum force. When does this occur?

The work done in rotating the magnet form the direction of uniform field to the opposite direction to the field is W . The work done in rotating the magnet form the field direction to half the maximum couple position is
