If Earth’s magnetic field disappeared, the entire human race – and all of life, in fact – would be in serious danger. Cosmic rays would bombard our bodies and could even damage our DNA, increasing worldwide risk of cancer and other illnesses.

Why does the South Atlantic anomaly exist?

The South Atlantic Anomaly is a weak spot in Earth’s magnetic field, which protects the planet from high doses of solar wind and cosmic radiation. This anomaly exists because the Earth’s inner Van Allen radiation belt comes closest to the planet’s surface, causing an increased flux of energetic particles.

Does the South Atlantic Anomaly move?
