It’s Official: Earth’s Magnetic North Pole Just Changed Position, and It’s Drifting Into Uncharted Magnetic Territory
Key Points:
- The magnetic north pole has officially shifted from near Canada to closer to northern Russia, completing a 2,200-kilometer drift that began over 190 years ago, according to the World Magnetic Model 2025 by NOAA and the British Geological Survey.
- The pole's movement has decelerated sharply from speeds of up to 60 km per year in the 1990s to about 35 km per year, marking the largest deceleration in recorded pole speed due to changes deep in Earth's molten outer core.
- The updated World Magnetic Model includes a new high-resolution version (WMMHR2025) with improved spatial detail for polar regions, enhancing navigation safety for aviation, military, and other high-latitude operations.
- The model is critical for global navigation systems, affecting everything from commercial flights and military positioning to smartphone compass apps, especially in environments where GPS signals are weak or unavailable.
- Despite ongoing shifts in the magnetic field, there is no indication of an imminent geomagnetic reversal; instead, the field is in constant motion driven by core dynamics and solar interactions, necessitating regular model updates.
