Earth’s magnetic field: Explained | Space

Earth’s magnetic field — also known as the geomagnetic field — is generated in our planet’s interior and extends out into space, creating a region known as the magnetosphere.

Without the magnetic field, life on Earth as we know it would not be possible as it shields us all from the constant bombardment by charged particles emitted from the sun — the solar wind. (To learn what happens to a planet when it loses its magnetic field, you only need to look at Mars.)
