A long magnet is cut in two parts in such a way that the ratio of their lengths is 2:1. The retio of pole strengths of both the section is

A large magnet is broken into two pieces, so that their lengths are in the ratio 2:1. The pole strengths of the two piece will be

The pole strength of a bar magnet is 300 units. It is cut into two pieces A and B along a line parallel to its axis in such a way that the breadth of A is double the breadth of B. Then the pole strengths of A and B are in the ratio

A large magnet is broken into two pieces so that their lengths are in the ratio 2:1 .The pole strengths of the two pieces will have ratio

If the magnet is cut into four equal parts such that their lengths and breadths are equal . Pole strength of each part is

If the magnet is cut into four equal parts such that their lengths and breadths are equal . Pole strength of each part is

A large magnet is broken into two pieces,so that their length are in the ratio 2:1.The pole strength of the two piece will be in the ratio

A bar magnet of magnetic moment M is cut into two parts of equal lengths. The magnetic moment and pole strength of either part is

Two long bar magnets are placed with their axes coinciding in such a way that the north pole of the first magnet is 2.0cm from the south pole of the second. If both the magnets have a pole strength of 10 Am , find the force exerted by one magnet on the other.
