A rendering of the magnetic field lines of Earth's magnetosphere. A magnetosphere is the region of space surrounding an astronomical object in which charged particles are controlled by that object's magnetic field. Near the surface of many astronomical objects, the magnetic field resembles that of a dipole.
The Earthâs magnetic field is the magnetic field that surrounds the Earth. It is sometimes called the geomagnetic field. The Earthâs magnetic field is created by the rotation of the Earth and Earth's core.It shields the Earth against harmful particles in space. The field is unstable and has changed often in the history of the Earth. The magnetic field creates magnetic poles that are near the geographical poles.he Earthâs magnetic field is created by the rotation of the Earth and Earth's core.
