A magnetometer needle aligned with the horizontal component of Earth’s magnetic field deflects by an angle 45 when placed
on the axial line of a bar magnet of length 5cm . If the distance between the centre of the bar magnet abd the magnetometer needle is 100cm , the momnet of the bar magnet is ? bh- 0.36 * 10^-4 T
