A bicycle tour corresponds to the model of elementary magnets.

The bicycle tour

Have you ever ridden your bicycle with a larger group of people? Imagine you and your school class go on a bike tour. When the bikelane is next to a street, everybody coming towards you will see your front lights. On the other hand, everybody overtaking you will see your tail lights.

That means you are working exactly like the model of a magnet. The model of the elementary magnets describes a magnet as consisting of very many “mini magnets“, so-called elementary magnets. Like the bikes, they all face the same direction and cause the magnet to have a north and a south pole. For example, if all elementary south poles point to the left, the whole magnet is alligned this way.
