The magnetic moment of a short bar magne...

The magnetic moment of a short bar magnet is `1*6Am^2`. It is placed in the magnetic meridian with north pole pointing south. The neutral point is obtained at `20cm` from the centre of the magnet. Calculate the horizontal component H of earth's field. If magnet be reversed i.e. north pole pointing north, find the position of the neutral point.
