Average Puzzle

Suppose you are in a room with no metal objects except for two iron rods. Only one of them is a magnet.
How can you identify which one is a magnet? 

Answers are expected as comments


  1. Try to break the items if possible then bring them closer, the magnet will repel strongly.

    Or hang both the rods using one thread, the one which keeps the same direction in many attempts will be the magnet.
