Earth's north magnetic pole has officially shifted

Earlier, scientists from the US National Oceanic and Atmospheric Administration and the British Geological Survey updated the coordinates of the magnetic north pole, saying it was gradually leaving the Canadian Arctic behind and moving toward Russia's Siberia at a rate of over 55 km per year, up from less than 15 km in the year 2000.

Magnetic field variation is normal, if not easily predicted, but changes typically don't throw off navigation systems enough to warrant more frequent updates to the model. "Smartphone and consumer electronics companies also rely on the WMM to provide consumers with accurate compass apps, maps, and Global Positioning System services", explains NCEI.

This shift of magnetic pole is an emerging issue for all smartphone makers as the device compasses are getting more inaccurate by the day. The last version was released at the end of 2014 and was expected to last until 2020. At the end of 2017, it crossed the worldwide date line.

For decades, magnetic north was steadily inching away from the geographic North Pole, but for the last few years the north magnetic pole has been moving closer to the North Pole.

Since 2015, the place to which a compass points has been sprinting toward Siberia at a pace of more than 30 miles a year.

"Airport runways are perhaps the most visible example of a navigation aid updated to match shifts in Earth's magnetic field". The update doesn't have much effect for civilian users of magnetic navigation but is critical to military users.

The World Magnetic Model is a model used to map out Earth's magnetic field. The one thing scientists can all agree upon is that the movement of magnetic poles is impossible to accurately forecast for the future.

The model, which is commissioned by the British and U.S. military agencies, is typically updated every five years, the most recent being in 2015.

Since 1831, the north magnetic has been moving across the Canadian Arctic towards Russian Federation, which is unlike the geographic north pole, which is fixed, NOAA reported.

The NOAA said Earth's magnetic field changes because of "unpredictable flows in Earth's core". The individual lines in red and blue show the magnetic field lines of Earth. Over the last 780,000 years, fossil records indicate that the poles have moved and switched a number of times, with no recognizable harm to living organisms. The military depends upon where magnetic north is intended for navigation and parachute drops, whereas NASA, the Federal Aviation Administration and the US Forest Service use it.

Also, migratory animals such as birds, butterflies, and whales use the magnetic field for directions. Only by tracking it, said University of Leeds geophysicist Phil Livermore, can scientists hope to understand what's going on. This liquid iron is in constant motion due to Earth's rotation and various other reasons, and this motion produces a magnetic field.
