उत्तर
If a bar magnet is hung by a thread tied at its centre, its north pole becomes steady in the direction of the South pole of the earth.
Explanation:
When a bar magnet is suspended, its north pole points towards the Earth's magnetic south pole (near the geographic north pole). This happens because opposite magnetic poles attract.
