Changes within the magnetic field and the Earth’s core are happening so rapidly that the World Magnetic Model is in dire need of an update.
On the left is a normal dipolar magnetic field, typical of the long years between polarity reversals.
The Earth’s magnetic field is on the move, with the North Pole shifting and currently on its way to Siberia. These maps are available for download in pdf format by clicking on the browse images below or you can download a zip file containing all of the map pdfs with or without the blackout zones.
And, as a bonus, … Above: Supercomputer models of Earth's magnetic field. We monitor the Earth's magnetic field.
