A bar magnet of length $\displaystyle 14$ cm is placed in the magnetic meridian with its north pole pointing towards the geographic north pole. A neutral point is obtained at a distance of $\displaystyle 18$ cm from the center of the magnet. If $\displaystyle \mathrm{B}_{\mathrm{H}}=0.4 \mathrm{G}$, the magnetic moment of the magnet is $\displaystyle \left(1 \mathrm{G}=10^{-4} \mathrm{~T}\right)$
