A bar magnet of magnetic moment `1.5J//T` lies .aligned with the direction of a uniform magnetic field of 0.22 T? What is the torque on the magnet if it is aligned opposite to the direction of magnetic field?

A bar magnet of magnetic moment 1.5J//T lies .aligned with the direction of a uniform magnetic field of 0.22 T. What is the torque on the magnet if it is aligned normal to the magnetic field?

A bar magnet of magnetic moment 1.5J//T lies .aligned with the direction of a uniform magnetic field of 0.22 T.What is the amount of work required by an external torque to turn the magnet so as to align its magnetic moment: opposite to the field direction?
