उत्तर
- Tie a thread to the centre of the magnet and hang it freely from a stand.
- Wait for the magnet to settle. As it hangs, it will align itself along the Earth's magnetic field in a north-south direction.
- The end of the magnet that points towards the geographic north will be the south pole of the magnet (since opposite poles attract).
Therefore, the other end, which points toward the geographic south, will be the north pole of the magnet.
