Question

a. A bar magnet has no markings to indicate its poles. How would you find out near which end is its north pole located?

Answer 1

Answer:

The location of the poles as the magnet can be determined by suspending it freely. A freely suspended bar magnet always points in a north−south direction. The end that points towards north direction is the north pole of the magnet while the end that points towards the south direction is the south pole of the magnet.
