Question

Why compass always align itself in approximately north–south direction?

Answer 1

The Earth is like a giant magnet. the centre core contains iron, and as it moves, it creates an electric curent that causes a magnetic field around the Earth. The Earth has a north and south magnetic pole which is opposite to the geographic north and south.

A compass needle on the surface of the Earth will point along the magnetic field lines, towards the north magnetic pole.compass needle behaves like a tiny magnet and as opposite poles attract south of compass needle(i.e. geographic south) points to the earth's magnetic north and vice versa.

Answer 2

Heyy PrincesS! ^_^
_____________
The Needle of compass is made from magnetic material and can change its position in magnetic field when experienced force . The Needle align itself in North-South Direction Because the magnetic intensity is greatest at poles .So One end of needle point towards North while other end to South Direction .
