When the solar wind comes to the earth it meets the Earth's magnetic field. Most of the tiny particles in the solar wind are pushed around the earth because of this magnetic field. They begin their journey around in a curve called the "Bow Shock". Just like water makes a curved wave in front of a boat, the solar wind makes a curve in front of the Earth.
After passing through a shock wave at the bow shock, the wind flows around the magnetosphere and stretches it into a long tail. However, some solar wind particles some how come in through the magnetic barrier and are trapped inside. Solar…
