Neutral Points

A bar magnet is placed with its North pole pointing North. Neutral point is at 12 cm . Another magnet is now placed on the first magnet, then the neutral point is found to be at 8 cm . The ratio of their magnetic moments is

Given below are two statements. Which of the state meants is/are true ? Statement-A : when the south pole of a bar magnet points towards the geographic north pole, the neutral points are along the equatorial line Statement B: At the neutral point, the Earth's magnetic field is zero .

A bar magnet is placed with its North pole pointing North. Neutral point is at a distance 'd' from the center of magnet. The net magnetic induction at the same distance on the axial line of the magnet is

With you help of neat drawn diagrams, explain how will you locate the neutral points due to a bar manget when (1) its north pole points towards geographic north? (2) Its south pole points towards geographic north ?

A short bar magnet is placed in magnetic meridian with its north pole pointing toward south: Its magnetic moment is 2Am^(2) . Neutral point is obtained 10cm from centre of magnet toward north. Calculate horizontal component of earth's magnetic field.

At a neutral point

A bar magnet is placed with its north pole towards geographic north. The neutral point
