perplexus.info :: Science : Magnetic Mystery

Magnetic Mystery (Posted on 2005-01-25)

You have two identical looking metal bars. One of them is a magnet, with North and South ends. The other is simply an iron bar (which is attracted by magnets).

How can you tell which is which, using only these two bars?
