A magnet suspended in a uniform magnetic field of induction `0.2" Wb/m"^(2)`, makes an angle of `60^(@)` with the normal to the direction of the field. What is the magnetic moment of the magnet, if a torque of moment `15xx10^(-2)` Nm acts on it?

A bar magnet of magnetic moment M is divided into 'n' equal parts cutting parallel to length. Then one part is suspended in a uniform magnetic field of strength 2T and held making an angle 60^(@) with the direction of the field. When the magnet is released the K.E of the magnet in the equilibrium position is
