Question

A short bar magnet is placed in the magnetic meridian of the earth with north pole pointing north. Neutral points are found at a distance of 30 cm from the magnet on the East - West line, drawn through the middle point of the magnet. The magnetic moment of the magnet in $\mathrm{A} \mathrm{m}^{2}$ is close to\ (Given $\frac{\mu_{0}}{4 \pi}=10^{-7}$ in SI units and $B_{H}=$ Horizontal component of earth's magnetic field $=3.6 	imes 10^{-5}$ Tesla.)\
