If you are using your smartphone to navigate, your system just got a crucial update. Scientists have released a new model tracking the position of the magnetic north pole, revealing that the pole is now closer to Siberia than it was five years ago and is continuing to drift toward Russia.
Unlike the geographic North Pole, which marks a fixed location, the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion. Over the past few decades, magnetic north’s movement has been unprecedented — it dramatically sped up, then in a more recent twist rapidly slowed — though scientists can’t explain the underlying cause behind the magnetic field’s unusual behavior.
Global positioning systems, including those used by planes and ships, find magnetic north using the World Magnetic Model, as it was named in 1990. Developed by the British Geological Survey and the National Oceanic and Atmospheric Administration, this model notes the established position of magnetic north and predicts future drift based on the trajectory of the past few years. To preserve the accuracy of GPS measurements, every five years researchers revise the WMM, resetting the official position of magnetic north and introducing new predictions for the next five years of drifting.
