Earth's magnetic north pole is rapidly moving away from the Canadian Arctic towards Siberia. NCEI scientists (¹) updated the global magnetic model (WMM) 2025.
The position of the geomagnetic North Pole is 80.8°N in latitude and 138.6° E in longitude
March, the World Magnetic Model (WMM) is published every five years. The official revision of the WMM 2025 was published on 17 December. Its role is to ensure navigation safety for military applications., commercial airlines, search and rescue operations and others operating around the North Pole.
The smartphone companies and consumer electronics are also based on the WMM to provide users with the magnetic variation for compasses, electronic compasses, maps and GNSS services. This is particularly essential for maritime navigation applications. (²).
The West Indies currently have a declination between 15° and 16° West. The magnetic 0° crosses Finistère, Paris is 2° East.
The compass use variation (the difference between true north and magnetic north of where the compass is located) to help correct navigation systems for a wide variety of uses. As Earth's magnetic field evolves between the 5 -year release schedule of the WMM, these predicted values can become off as the rate of change in Earth's magnetic field evolves due to unpredictable flows in Earth’s core. The North Polar Region is experiencing one of these erratic changes.
