Earth’s magnetic field

Aurora Borealis Aurorae | Aurora Australis

An effect caused by the Earth’s magnetic field is the spectacular Northern and Southern Lights, which are also called the Aurora Borealis (Figure 1) and the Aurora Australis respectively (Figure 2). When charged particles from the solar wind reach the Earth’s magnetosphere, they spiral along the magnetic field lines towards the North and South poles. […]

The importance of the Earth’s magnetic field to life on Earth

The Earth’s magnetic field is very important for humans and other animals on Earth because it protects us from being bombarded (struck) by high-energy charged particles, which are emitted by the Sun. The stream of charged particles (mainly positively charged protons and negatively charged electrons) coming from the Sun is called the solar wind. When […]
