Question A short bar magnet is placed in the magnetic meridian of the earth with a north pole pointing north. Neutral points are found at distance of 30 \( \mathrm{cm} \) from the magnet on the East - West line, drawn through the middle point of the magnet. The magnetic moment of the magnet in \( \mathrm{Am}^{2} \) is close to (Given \( \left(\mu_{0} / 4 \pi\right)=10^{-7} \) in SI units and \( B_{H}= \) Horizontal component of earths magnetic field \( = \) \( 3.6 \times 10^{-5} \) Tesla.)
(A) 9.7
(B) 4.9
(C) 19.4
(D) 14.6📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
