Question

Why does a freely suspended bar magnet always comes to rest in the north-south direction ?

Answer 1

This suggests that the Earth itself behaves as a magnet which causes a freely suspended magnet (or magnetic needle) to point always in a particular direction: North and South. ... The South Pole of the Earth's magnet is in the geographical North because it attracts the North Pole of the suspended magnet and vice versa.

Answer 2

bar magnet have two sides North and South when you join South to South it repal but when u jion South to north it's attech because of its nature
