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?

pick one bar up and try to stick it to the closest thing medal, if it sticks, its the magnet: if not then there is the iron
