Okay... so if you have the metal bar and move one end of the magnetic bar along it, there should always be an attraction/repulsion between the two. But if you do this vice versa, moving hte metal bar along the magnet, then once you get to the middle there should be no attraction/repulsion at all?

I have what is hopefully a quick question. Using only an unmarked magnetic bar and an identical metal bar, suggest a way to find out which is the magnet and which is the metal bar. This is supposed to be in a room with nothing but these two materials. Any help is greatly appreciated!
