Magnetic north pole accelerates towards Siberia

February 6, 2019 -- Magnetic north is on the move, forcing an emergency update for GPS systems which need its precise location to function accurately.

Earth’s magnetic North Pole is moving far faster than it has before, forcing scientists to issue an emergency update for the World Magnetic Model, critical to sea and military GPS navigation, as well as gadgets like smartphones.

It is normally updated every five years but the schedule has been pushed forward a year due to the accelerated rate at which the pole is moving.

The wandering magnetic north pole, which long jiggled above Canada and barely moved, is now moving 48km a year towards Siberia. Since the 1990s, the movement has accelerated from about 15km a year to 50-55km a year.

Earth’s magnetic field is generated mainly by movement of the liquid iron that makes up most of our planet’s core, some 3,000km beneath the surface. That movement causes the magnetic poles to shift, but the cause of recent acceleration remains unknown.


NEW GRAPHIC NEWS - a new website for a new era, coming soon…

And it will be worth the wait! The Graphic News website is undergoing a complete redesign. The new site will not only see improvements in terms of speed and user experience, but will also include many new features. For example, existing subscribers will be able to manage their accounts online via a group dashboard, and add selected graphics to lists for project planning (and which can be shared across the group).

Existing users will need to register individually - we’ll be sending instructions to our main contacts at each group and will be on hand to help you through the process, which we hope will be seamless!
