Does the Earth have a magnetic field?
The Earth’s magnetic field is called the magnetosphere. If Earth didn’t have a magnetic field, it is doubtful we would be writing to each other. The Earth’s magnetic field protects us from harmful radiation and energy from the Sun. A magnetosphere is the region surrounding a planet where the planet’s magnetic field dominates. Because the ions in the solar plasma are charged, they interact with these magnetic fields, and solar wind particles are swept around planetary magnetospheres. Life on Earth has developed under the protection of this magnetosphere.
