उत्तर
A freely suspended bar magnet always comes to rest in the North−South direction. The north-facing end of the magnet is its north pole, and the south-facing end is its south pole (as shown in the given figure).
Hence, the unknown poles of a bar magnet can be marked by suspending it freely by a string.
