A short bar magnet of moment 4 Am^2 is kept in the magnetic meridian with it's north pole pointing geographic north.The distance between two null points is found out to be 20 cm.
1)The value of horizontal component of the earth's magnetic field at that place is:.....4G
2)In the above problem,if the magnet is replaced by another one of double the length and thrice the pole strength ,the value of the horizontal component of the earth's magnetic field at that place is .....24G (the given answer is 4G)
