In two separate experiment the neutral point due to two small magnets are at a distance of r and 2r in broad side-on position. The ratio of their magnetic moments will be

In a deflection magnetometer experiment the deflections produced separately by two short bar magnets kep at the same distance are 45^(@) and 30^(@) . Then, the ratio of the magnetic moments of the two magnets is

The magnetic potential at a point due to pole of strength m at a distance r is

The ratio of the magnetic fields due to small bar magnet in end position and on broad side position is (at equal distance from the magnet)

The ratio of the magnetic fields due to small bar magnet in end position and on broad side position is (at equal distance from the magnet)

The ratio of the magnetic fields due to small bar magnet in end position an broad side on position is (at equal distance from the magnet)

The ratio of magnetic intensities at points at equal distance on end - on position and broad -side -on position of a short bar magnet is

Derive the expression for the magnetic field intensity due to a bar magnet at any point on its board side-on position. Find the same when the length of the magnetic field intensity due to a bar side-on position. Find the same when the length of the magnet is small.
