Hoping to keep tabs on the magnetic north’s wandering ways, the World Magnetic Model 2025 has been released this week, revealing the latest official predicted placement of Earth’s magnetic fields. This version will remain valid until late 2029, during which time we can expect to see the magnetic north pole slowly edge further toward Russia.
The new version is of timely importance too as the magnetic north pole’s movement seems to be accelerating.
Since the 1830s, the north magnetic pole of Earth has relocated some 2,250 kilometers (1,400 miles) across the upper stretches of the Northern Hemisphere from Canada towards Siberia. Between 1990 and 2005, the rate of pole movement increased from less than 15kilometers (9.3 miles) per year to around 50 to 60kilometers (31 to 37 miles) per year.
“The current behaviour of magnetic north is something that we have never observed before. Magnetic north has been moving slowly around Canada since the 1500s but, in the past 20 years, it accelerated towards Siberia, increasing in speed every year until about five years ago, when it suddenly decelerated from 50 to 35 km per year, which is the biggest deceleration in speed we’ve ever seen,” added Dr Brown.
