How will we find out the north pole and south pole of a bar magnet with no markings to indicate poles?

Description : How will we find out the north pole and south pole of a bar magnet with no markings to indicate poles?

Last Answer : If you roughly know where North is, tie the bar magnet to a piece of thin string so it balances horizontally and let it dangle. Once it stops spinning and waving about, one end should point North. Mark this end as with an N for north.
