How does the Earth's magnetic field protect us?

Transcript

The Earth's magnetic field protects us by creating a magnetosphere that deflects harmful solar radiation and charged particles from the solar wind. This magnetic shield prevents these particles from stripping away the atmosphere and reaching the Earth's surface, thereby preserving the ozone layer, which protects us from ultraviolet radiation. Without this protective barrier, life as we know it would be at severe risk from solar and cosmic radiation.
