Answer:
Well, an easy way to tell the south pole from the north pole in a magnet would be to use a compass. After finding the magnetic north, put one side of the magnet that you'd like to test close to the needle side indicating the north. If the needle is attracted by
your magnet it means you presented the north pole face of your magnet to the needle
of the compass. Otherwise you presented the south pole face. By inscribing a N (means north) to the north face of your newly identified magnet and a S to the other face, you
can now identify any magnet face by that simple rule: opposite attract each other!
