Earth's magnetic field Characteristics Magnetosphere
The magnetosphere is created by the magnetic field. It is the area around the Earth that acts as a shield against the harmful particles in solar wind. The magnetosphere has many different layers and structures, and solar wind shapes each of these layers. The interaction of solar wind and the magnetosphere also causes the Northern and Southern Lights to appear. The magnetosphere is very important in protecting the Earth against solar storms which increase solar wind activity. Solar storms can cause geomagnetic storms which sometimes have serious affects on the Earth.
