What are the magnetic poles?

In the magnet, the magnetic force is concentrated at the ends and weaker in the middle. These magnetically strong ends are called magnetic poles. The magnets have two poles, both with the same strength. The Earth also has magnetic poles. The compass works because the magnet in the compass responds to the magnetic power of the Earth.

A simple molding magnet allowed freely to rotate freely with the magnetic northern and southern poles of the Earth. Some magnets are marked n at one end and on the other. This is because the end n will always point north, while the end S will always point south. If the two magnets are placed side by side, the end of the first magnet attracts the end with the other, while the ends of n repel each other.

The Earth's magnetic poles are so strong that the magnet will always be in line with poles no matter how far away from them. It should be noted that the Magnetic North Pole of the Earth does not settle pervituctly with the geographical North Pole. Magnetic north is actually about 15 degrees from geographical withEver.

For thousands of years, people have been using the Earth's magnetic poles to help them navigate. The compass is basically a free rotating needle. Because the needle is magnetized, it will always point north. Knowing which direction is the north, explorers and travelers can find out which direction they occur. The first mention of the compass was the ancient Chinese around 210 BCE.

There are several different theories that explain why magnets behave as they do. The older one is Weber's theory. It states that magnetic substances are made of small magnetized molecules. When they leave alone, these molecules show in all different directions. If the magnet is dragged over the material several times moving in the same direction, the molecules are aligned as a series of magnets to the northern end to the southern end, creating magnetic poles at both ends of the metal.

a similar but more sophisticated theory with the relevantHe knows that electrons have magnetic fields. Electrons are small units that circulate around atoms. Each atom has at least one electron. The domain theory states that if the electrons of the atom circulate in all different directions, their magnetic fields will cancel each other. However, if they orbit the same direction, the atom will be magnetized. The material full of these magnetized atoms is a magnet.
