Magnetic field reversal on Earth
Numéro d’image : 11736265
| Model of geomagnetic field reversal. Third of three frames showing the magnetic field structure produced by a numerical simulation of the geodynamo,the source of the Earth's magnetic field. Here,the simulation has run for 40,000 'years',and is seen after a field reversal. The colours represent field lines with outward (yellow) and inward (blue) components. Magnetic field reversals are a feature of Earth's history,and are recorded in rocks near mid-ocean ridges. This image is from a paper published in 'Nature' in September 1995.
