This simulation shows the Earth's magnetic field as a
dipole, generated by electric currents in the liquid outer core.
The field protects us from harmful solar wind and cosmic radiation,
creating the magnetosphere.
The magnetic axis is tilted about 11.5° from the
rotation axis (True North).
Did you know? The Earth's magnetic field reverses every
few hundred thousand years.
The Van Allen belts trap charged particles, protecting life on Earth.
