Answer:
Earth itself behaves like a huge bar magnet with its magnetic poles near the geographical north and south poles. ... Therefore, when a magnet is suspended freely, the magnetic poles of the earth attract the opposite poles of the magnet and the magnet comes to rest in the north-south direction.

Answer:
The Earth behaves like a magnet because the Earth is a magnet. It is not a permanent magnet, but an electromagnet. We now understand why. Deep in the Earth, molten metal (mostly iron) flows due to heat which causes convection.
