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?

The problem stated "using only these two bars"......NOT "using only these two bars and any fridge that happened to be handy".
