Write analogy between electrostatic and magnetism.

A short magnet of moment $6.75\, Am^2$ produces a neutral point on its axis. If horizontal component of earth's magnetic field is $5 \times {10^{ – 5}}\,Wb/{m^2}$, then the distance of the neutral point should be…..$cm$

Which statement is correct 

The magnetic field lines due to a bar magnet are correctly shown in

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