A look inside

In the model of elementary magnets the effects of magnets are illustrated by so called elementary magnets. This can be imagined as if there were countless „mini-magnets“ in the magnet, as in the opposite illustration.

Where do you think are the poles of the illustrated magnets?
Pick one of the following five magnets and make a simple sketch, in which you mark its poles. Then click on the magnet below to see the solution.
If you do not have any idea on how the magnets are poled, move your cursor over the magnet on the right to look at an example. Hint: Not all of the following objects are magnets.
