How to identify a magnet from a metal bar

[OAR404]

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!

Hint: the middle of the bar magnet is not "magnetized".

Zz.

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?

Very close! But one tiny detail is wrong.

there should always be an attraction/repulsion between the two

It's only one of those two possibilities. Which one?
