The earth behaves as a magnet with magnetic field pointing approximately from the geographic
A short bar magnet is placed in the magnetic meridian of earth with its north pole pointing towards 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 approximately equal to _____(Given μ04π=10−7 in SI units and BH = Horizontal component of earth's magnetic field = 3.6×10−5 tesla)
