A short bar magnet is placed in the magnetic meridian of 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 Am² is close to $\left(\begin{array}{l}\mathrm{Given}\frac{{\mathrm{\mu }}_{\mathrm{o}}}{4\mathrm{\pi }}={10}^{-7}\mathrm{in}\mathrm{SI}\mathrm{units}\mathrm{and}{\mathrm{B}}_{\mathrm{H}}=\mathrm{Horizontal}\mathrm{component}\mathrm{of}\\ \mathrm{earth}\text{'}\mathrm{s}\mathrm{magnetic}\mathrm{field}=3.6\times {10}^{-5}\mathrm{tesla}\end{array}\right)$
