Earth As A Magnet
We know that freely suspended magnetic needle always rests in north-south direction. It is due to the reason that the earth itself behaves like a huge bar magnet. The south pole of this bar magnet is near the geographic north pole and the north pole of this bar magnet is near the geographic south pole.
The north pole of a freely-suspended magnet points towards the geographic north pole because it is attracted by the magnetic south pole of the earth. Similarly, the south pole of a freely suspended magnet points towards geographic south pole because it is attracted by the magnetic north pole of the earth.
