Earth’s Magnetosphere

Earth’s magnetosphere is a protective magnetic field generated by the planet’s liquid iron core. It extends outward into space and acts like a shield against solar wind—charged particles emitted by the Sun. When solar wind interacts with the magnetosphere, it is deflected around Earth, preventing most particles from reaching the surface. This magnetic shield also creates phenomena like the auroras (Northern and Southern Lights). The magnetosphere's shape varies with solar activity, stretching on the side away from the Sun and forming a protective bubble that preserves conditions suitable for life on Earth.
