Q7. A bar magnet has no markings to indicate its poles. How would you find out near which end is its north pole located?
A freely suspended bar magnet always comes to rest in a particular direction, which is the North-South direction. So if there is no marking then the end of a magnet pointing to the north is the north pole of the magnet.
