Wherever we are in the world, we can always find our way through the compass in a very easy way. Even if we were in the middle of the ocean, it would take us a few seconds to find our way through this simple device. Nowadays the compass has always been the easiest way even though there are very sophisticated devices such as GPS satellites. The compass has a magnetic arrow that is balanced and placed on top of the needle so that it can move almost without friction. This arrow, thanks to magnetism on the Earth's North magnetic field (North magnetism), always shows the north.
We can think of the world as a great magnet. The magnetic field of the world is directed to a certain order in the formation process and shows a magnet characteristic. Accordingly, the North Pole is directed as S. The South Pole is also directed at N. The letters N and S used in magnets are also inspired by the North and south poles.
The compass is marked as N, north of the Arrow, and the north of the compass draws the northern world from the principle of different poles pulls each other. In order to feel this shot on the surface of the world with an 8000mile diameter, the compass arrow is extremely light and is not friction-free. Otherwise, it would not be possible to navigate by the magnetic field.
Along the entire axis of the world, the compass does not work with 100% accuracy, some areas are deviating. These regions and how much deviation are shown in detailed maps.
One consideration when using the compass is the absence of metal objects that can be used to create magnetic fields around it. If the magnetic field around the compass has an object that is more than the surface of the earth, the compass arrow is directed towards that object. This also means faulty measurement.
History
The Chinese invented the compass in 100 A.D. The discovery of the compass took place from the principle that a freed object would be headed north in a magnetic environment.
In France, the first compass was mentioned in 1200. It was followed by Iceland in 1207, England and 1213. The compass had a primitive structure. The first significant development was Pierre de Maricourt (1269). After he put the needle in a metal stick, he planted it in a transparent and graded box.
