📄𝐓𝐞𝐱𝐭:
As you know, the Sun always sets in the west. So, this gives a way of finding the other cardinal directions too – north, south and east. But if you have a compass, you might notice that the north you find according to the Sun, and the north to which the compass points, aren’t exactly the same. The north you find with respect to the Sun is called geographic north or true north, whereas the north shown by the compass is known as magnetic north. And these two norths are different.
Geographic north lies in the direction of the North Pole – the point where Earth's axis of rotation cuts through the surface. This point marks the center of the northern hemisphere and is located in the frozen middle of the Arctic Ocean.
Magnetic north, on the other hand, is the direction of the point on Earth’s surface where Earth’s magnetic field points vertically downward. Because Earth is like a giant magnet, compasses point toward the magnetic poles. These poles are not in fixed positions. Today magnetic north is located near the geographic North Pole. In 1900, though, it was located on Canadian soil and today it’s moving towards Siberia in Russia.
