Bar Magnets

Obtain the Earth’s magnetisation assuming that the Earth’s field can be approximated by a giant bar magnet of magnetic moment 8.0xx10^22Am^2 .The Earth 's radius is 6400 km.

A short bar magnet is placed along N-S direction with N pole pointing north. The neutral points are located 20 cm away from the bar magnet. If B_(H) is the horizontal component of earth's magnetic field then the magnetic field due to the bar magnet at distance of 40 cm along its axis is
