A bar magnet with its poles 25 cm apart and of pole strength `24.0 A-m` rests with its centre on a frictionless pivot. A force F is applied on the magnet at a distance of 12 cm from the pivot, so that it is held in equilibrium at an angle of `30^(@)` with respect to a magnetic field of induction 0.25 T. The value of force F is
