Question

why does the magnet come to rest in that particular direction only​

Answer 1

Answer:

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.
