Expert Answer:

Magnetise an iron needle using a bar magnet. Now, insert the magnetized needle through a small piece of cork. Let the cork float in water in a bowl or tub. Make sure that the needle does not touch the water. The magnetised iron needle fixed in the cork floating on water has become a compass. It will align itself along the north-south direction.
