You have two bars of metal placed upon a table, 10cms in length and 2cms square.They are identical in every aspect apart from the fact that one of them is a magnet.When they are moved close to each other they seem to attract each other. Without removing them from the table, and with no other aids, how do you tell which is the magnet

I would try this:
The end of the magnet would attract the center of the bar, but the end of the bar would not attract the center of the magnet.

The tip of the real magnet will attract the center of the non-magnetic bar while the tip of the non-magnetic bar will not attract the center of the magnetic bar.

take each bar and hold it to a different piece of metal. which ever one sticks to the metal is your magnet.
