How compasses work?
1. The origin of the word compass comes from small box. The compass was discovered in China around 1050.
2. A compass points toward the magnetic north pole, which is slightly different from the geographical North. For precise measures, you sometimes need to adapt the indication given by the compass. If you often use the compass, make sure to measure it regularly.
3. Never put a compass near a metal object (such as a watch, a ring, a table...). A compass cannot find its way with metal.
4. Never put two compasses next to one another: they will demagnetize and then show a wrong direction (you simply need to separate them to make them work again).
5. For a reliable measurement, the compass has to be hold horizontally so that the needle can freely move.
