What is the Earth's magnetic field and its usefulness?

We often hear about the Earth's "magnetic field", its negative effects on satellites and its ability to destroy electronics without knowing what's useful. The following information may help to understand the importance of the Earth's magnetic field.

Many scientists have confirmed that the electric currents in the Earth's molten iron core as well as the natural motion resulting from the Earth's rotation lead to a magnetic field.

Physicists have stated that the Earth can be described as a general physical image, a large magnet emitted by its own magnetic field, called the magnetic field of the Earth that surrounds the planet in the name of the magnetosphere and extends over 36,000 km in space.

The Earth's magnetic field is of great importance, especially with regard to the pursuit of life on Earth: it protects the Earth from charged particles and radiation from the outer surface of the sun, called the solar wind, which is actually a flux charged particles emanating from the atmosphere of the sun. And most often contain electrons and protons, and these particles are able to get out of the gravity of the sun due to the intense heat.

If there is no magnetic field to stop and dissipate this solar wind, the Earth will have no protection against these destructive forces, as it is a hidden shield that protects it from solar wind .

A number of studies have revealed that without the Earth's magnetic field, life on Earth would have been impossible and initially created on the planet. When scientists studied the rest of the planets of the solar system, they discovered that most of them had no magnetic space similar to that of the Earth. It is not protected from the solar wind that approaches it and penetrates easily, resulting in higher temperatures several hundred degrees to its surface.

It should be noted that the coordination of life on Earth has other advantages, some of which have been discovered and some are under study, where the phenomenon of the magnetic field still presents a certain ambiguity.
