How can we know which side is south in a bar magnet ??
Dear student.
We will suspend the given magnet freely with a thread and make to come to rest. It is fixed that all magnets rest in north south direction only.So after some time the end of the given magnet which points towards the north direction will be the north pole and the other end will be south pole ponting towards south.
Regards
