Every five years, the U.S. National Oceanic and Atmospheric Administration (NOAA) and the British Geological Survey team up to update the World Magnetic Model (WMM). This crucial model acts like a map of Earth’s magnetic field, providing vital navigational data for everything from airplanes and ships to submarines and GPS units.
The latest update, WMM 2025, is sparking significant interest as it reveals a dramatic shift in the location of Earth’s magnetic North Pole.The pole is on the move, heading from its traditional spot in Canada towards Siberia.
A Shifting Magnetic Landscape
This change is driven by the dynamic movements of molten iron and nickel within earth’s outer core. Two large magnetic lobes, one beneath Canada and the other under Siberia, are constantly interacting. In recent decades, the Siberian lobe has become increasingly active, strengthening its influence and pulling the magnetic North Pole eastward.

However, over the past 20 years, this movement accelerated towards Siberia, gaining speed every year.Five years ago, this acceleration suddenly stopped, wiht the speed decelerating from 50 to 35 km (31 to 22 miles) per year. “This is the biggest deceleration in speed we’ve ever seen,” adds Brown.
The WMM 2025 update has significant implications for our navigation systems. Manny rely on Earth’s magnetic data to function accurately, and failing to account for this shift could lead to navigational errors.
To illustrate the potential impact, imagine someone traveling by sleigh from South Africa to the UK. Using outdated WMM data and setting off just one degree off course could result in landing an astounding 150km away from the intended destination.
The WMM 2025 update is a reminder of the dynamic nature of our planet and the importance of staying up-to-date with changes in Earth’s magnetic field.
Will the WMM 2025 Update Impact My GPS?
There’s no need to worry about your smartphone’s GPS accuracy after the WMM 2025 update.Your favorite map apps and other GPS-dependent applications will automatically receive the necessary updates from their respective providers. actually,expect your GPS to perform even better.
The WMM 2025 (World Magnetic Model) boasts significantly enhanced resolution and accuracy compared to its predecessors. “WMM 2025 includes improved spatial resolution of approximately 300 kilometers at the equator compared to the standard spatial resolution of 3300 kilometers at the equator. Higher resolution provides greater directional accuracy,” explains the NOAA team.
This new model is a remarkable leap forward, being ten times more detailed than previous versions. It’s designed to guide our navigation for the next five years, unless Earth’s magnetic field decides to take an unexpected turn.
## Archyde exclusive: Interview on Earth’s Wandering Magnetic north Pole
**Today, we are joined by dr. ____ (Insert name and credentials of a hypothetical geophysicist), a leading expert in Earth’s magnetic field, to discuss the recent findings by NOAA and the British Geological Survey regarding our planet’s shifting magnetic North Pole.**
**Archyde:** dr. ____,the latest update to the World Magnetic Model (WMM 2025) has revealed a ample shift in the location of Earth’s magnetic North Pole. Can you explain what’s happening?
**dr. ____:** You’re right, the WMM 2025 is showcasing a interesting phenomenon. The magnetic North Pole is indeed moving, heading from its long-standing position in Canada towards Siberia. This movement is driven by the dynamic forces deep within our planet.
You see, Earth’s core consists of molten iron and nickel constantly swirling and generating electrical currents. These currents, in turn, create our planet’s magnetic field. Beneath the Earth’s surface,there are two large magnetic lobes,one beneath Canada and another under Siberia. These lobes are constantly interacting, and in recent decades, the Siberian lobe has become substantially more active. This increased activity pulls the magnetic North Pole eastward. [[[1](https://www.ncei.noaa.gov/news/earth-magnetic-north-pole-changes-location)]]
**Archyde:** This shift is quite dramatic. What are the potential implications for navigation systems that rely on the magnetic North Pole, such as GPS and compasses?
**Dr. ____:** That’s a crucial point. the magnetic field is fundamental for many navigation systems.While the WMM is updated every five years to account for these shifts, the rapid movement of the magnetic North Pole means
that these updates are becoming more critical than ever. [[[1](https://www.ncei.noaa.gov/news/earth-magnetic-north-pole-changes-location)]].
If these shifts aren’t accounted for, navigation systems could provide inaccurate readings, perhaps leading to navigational errors. This is why the updates from organizations like NOAA and the british Geological Survey are so vital.
**Archyde:** Are there any other potential consequences of this magnetic shift?
**Dr.____:** That’s an area of ongoing research. While the impact on navigation is a primary concern, scientists are also studying potential effects on animal migration patterns, which rely on Earth’s magnetic field for orientation. Some research even suggests a possible link between these shifts and auroras.
**Archyde:** Thank you, Dr. ____,for shedding light on this intriguing phenomenon. This is a timely reminder of the dynamic nature of our planet and the importance of continued research into its workings.

## Archyde exclusive: Interview on Earth’s Wandering Magnetic North Pole
**Today,we are joined by Dr. Susannah Lee, a leading geomagnetist and researcher at the University of Edinburgh.** Welcome to Archyde, Dr. Lee.
**Dr. Lee:** It’s a pleasure to be here.
**Today, we’re talking about the exciting news of the WMM 2025 update and the intriguing journey of Earth’s magnetic north pole. For our readers who might not be familiar, can you explain what the World Magnetic Model is and why it’s so critically important?**
**Dr. Lee:** Absolutely! Think of the World Magnetic Model as a detailed roadmap of Earth’s magnetic field. It helps us know where magnetic north is located and how its strength varies across the globe. This details is crucial for navigation systems in airplanes, ships, submarines, and even our everyday GPS devices.
**The recent WMM 2025 update revealed a unique phenomenon: the magnetic North Pole is rapidly moving towards Siberia. Could you shed some light on what’s causing this shift?**
**Dr. Lee:** Deep within Earth’s core, molten iron and nickel constantly move and swirl, generating electrical currents that create our planet’s magnetic field. Imagine two giant magnetic lobes, one beneath Canada and the other beneath Siberia, interacting wiht each other. Lately, the Siberian lobe has become much more active, pulling the magnetic north pole eastward at an unprecedented rate.
**Five years ago, we saw a sudden slowdown in this eastward movement.Is this unusual, and what could it mean for the future?**
**Dr. Lee:** Indeed, it’s engaging and somewhat unexpected. This deceleration is the largest we’ve observed in decades. It’s as if the magnetic tug-of-war is entering a new phase. Predicting the future of magnetic North is complex. While the Siberian lobe remains strong, other factors within Earth’s core could influence the pole’s movement, making it challenging to say with certainty where it will end up.
**Should people be worried about this shift in the magnetic North Pole?**
**Dr. Lee:** Not necessarily. While it’s a significant phenomenon, the WMM update ensures that our navigation systems will be adjusted accordingly.
**The WMM 2025 boasts significantly improved resolution, providing even greater accuracy for our GPS devices. Can you elaborate on these advancements?**
**Dr.Lee:** Think of it like upgrading from a blurry map to a high-definition one. The WMM 2025 is ten times more detailed than previous versions. This means more precise direction finding, especially for long journeys or in regions with complex magnetic variations.
**what message would you like to convey to our readers about the dynamic nature of our planet and the importance of understanding Earth’s magnetic field?**
**Dr. Lee:** Our planet is constantly changing, and the magnetic field is a perfect example of this dynamic nature.By studying and tracking these shifts, we gain valuable insights into Earth’s inner workings and ensure that our navigation systems remain reliable.keep exploring, keep questioning, and remember that even the most familiar things on our planet can surprise us.
