jordmagnetisme
Jordmagnetisme refers to the magnetic field generated by the Earth. This field is primarily created by the motion of molten iron in the Earth's outer core, a process known as the dynamo effect. The resulting magnetic field extends from the Earth's interior to space, where it interacts with the solar wind, a stream of charged particles emitted by the Sun. This interaction gives rise to phenomena such as the auroras, which are visible near the Earth's magnetic poles.
The Earth's magnetic field is not static; it undergoes variations over time, including periodic reversals where
The magnetic field also plays a significant role in protecting the Earth from solar radiation and cosmic
Jordmagnetisme is studied through various methods, including satellite measurements, ground-based observations, and paleomagnetic studies. These studies
