Earth's electromagnetic field

Earth’s electromagnetic field is generated by the movement of molten iron and other metals in its outer core, creating electric currents. These currents produce a magnetic field, much like a giant bar magnet surrounding the planet. This field protects us by deflecting harmful solar radiation and charged particles. It also enables navigation with compasses and influences many natural phenomena, such as auroras. The magnetic poles gradually shift over time due to changes deep inside Earth. Overall, Earth’s electromagnetic field is a vital, natural shield that supports life and helps us better understand our planet’s interior processes.
