magnetosphere dynamics

The magnetosphere is the region around Earth controlled by its magnetic field, which shields us from solar wind—charged particles emitted by the Sun. When solar wind strikes the magnetosphere, it compresses on the sunward side and stretches into a long tail on the night side. These interactions can cause phenomena like auroras and occasional disruptions in satellites and power grids. The dynamics involve complex processes like magnetic reconnection, where magnetic field lines break and reconnect, releasing energy, and particle acceleration, which influences space weather. Overall, the magnetosphere acts as Earth's protective barrier, responding dynamically to solar activity.
