A short bar magnet is placed in the magnetic meridian of the earth with its 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 mid point of the magnet. What is the magnetic moment of the magnet in `Am^(2)`? (Given `m=10^(-7)` in SJ units and `B_(H)=` horizontal component of earth's magnetic field `=3.6xx10^(-5)` tesla)
