Connect the rods for several hours. The non-magnetized rod will be magnetized in this way.
The rods are touching. Remove one rod, and turn it around. If the one you are holding is the magnet it will repel the other rod. If both ends of the rod you are holding attract to the same end of the rod that it was attached to, it is not the magnet.

I thought about this all day, and after coming up with a solution I was surprised to come home and read that the provided solution actually seemed much more complicated than the one I came up with, it's usually the other way around.
Alternate solution: Break one or both rods and the one who's pieces attract or repel eachother is your magnet.
You can break metal bars then can you?
