The Wandering North: Why Earth's Magnetic North Pole Keeps Moving

Mr. G.K. Pooniyyaa, Lecturer Physics·13 November 2026·7 min read

Pick up a compass and the needle swings to "north". It feels like the most reliable thing in the world. But here is a surprise: the place your compass points to is not fixed. It is slowly wandering across the Arctic, and right now it is heading towards Siberia.

Let's understand this in simple words, and then see what our ancient Indian texts said about "fixed" things that move.

Two different North Poles

Most people don't know that Earth has two different North Poles:

Geographic North Pole: the top of the axis on which Earth spins. It stays in the same place, and it is the one marked on maps.
Magnetic North Pole: the spot where Earth's magnetic field points straight down into the ground. This is where your compass needle is pulled, and this one moves.

The gap between the two is why pilots, sailors and map-makers have to make small corrections when they use a compass.

How far has it moved?

The British explorer James Clark Ross first located the magnetic North Pole in northern Canada in 1831. Since then, it has travelled more than 2,200 km.

Here is its journey in simple steps:

For centuries it drifted slowly around northern Canada, usually about 10 km a year or less.
From the 1990s it suddenly sped up to about 50–55 km a year, crossed the Arctic Ocean and headed towards Russia.
In recent years it has slowed down to about 35 km a year. Scientists say this is the biggest slowdown ever recorded.
Today it sits closer to Siberia than to Canada, a big milestone after nearly 200 years of tracking.

"...the biggest deceleration in speed we've ever seen." William Brown, geomagnetic field modeller, British Geological Survey (via ScienceAlert)

Fun fact: In the 1980s the magnetic pole sat about 600 km north of Resolute in Canada, and adventurers could ski to it. Since the pole raced off over the Arctic Ocean, no one has skied to its real location (Explorersweb).

Why does it move?

About 2,900 km below our feet lies Earth's outer core, a huge ocean of hot, liquid iron and nickel. This liquid metal is always flowing and swirling. Moving metal creates electric currents, and electric currents create a magnetic field. So, in a way, Earth is a giant natural magnet powered by its own molten heart. Scientists call this the geodynamo.

Because the flow of liquid metal keeps changing, the magnetic field keeps changing too, and so the magnetic pole moves.

Researchers think two big magnetic patches (or lobes) deep inside the Earth are having a tug-of-war: one under Canada and one under Siberia. In recent decades the Canadian patch has become weaker, so the Siberian patch is winning and pulling the pole towards Russia.

The pole moves due to the "flow of molten iron and nickel between our planet's two large magnetic lobes." Deccan Herald, citing an Interesting Engineering report

Easy example: Imagine two children pulling a rope from both sides. If one child gets tired, the rope moves towards the stronger one. That is roughly what is happening under the Arctic.

Does it affect us?

For normal daily life, not really. But it matters a lot for navigation.

Every five years, NOAA (USA) and the British Geological Survey (UK) release the World Magnetic Model (WMM), a kind of official map of Earth's magnetic field. The latest version, WMM2025, came out in December 2024 and will be used until the end of 2029. It is used by:

Aircraft and ships for navigation
Armed forces and organisations like NATO
The compass app and maps on your smartphone

NOAA's 2025 WMM report notes "the slow drifting of Earth's magnetic north pole towards Siberia." NOAA NCEI

Without these regular updates, small compass errors would quietly add up, and planes or ships could drift off course.

Clearing up some myths

"It's caused by climate change." No. The movement comes from processes inside Earth's core, not from global warming or CO₂.
"The poles are about to flip!" Not necessarily. Earth's magnetic poles have flipped many times in the distant past (the last full reversal was about 780,000 years ago), but the current movement does not mean a flip is coming soon.
"It's dangerous." No. The magnetic field still protects us. It forms a shield in space called the magnetosphere, which keeps out most of the harmful charged particles coming from the Sun.

The movement is "linked to internal processes of the Earth's core, not to global warming." Noticias Ambientales

What do the Vedas and Upanishads say?

To be honest and clear: the Vedas and Upanishads do not talk about the magnetic North Pole. The idea of a magnetic field around Earth is modern science, so any claim that a Vedic verse "predicted" the magnetic pole shift should be treated with care.

But there is a beautiful and genuine connection: the idea of Dhruva, the Pole Star.

1. Dhruva, the symbol of the unmoving

In Indian tradition, Dhruva (the Pole Star) stands for something firm and fixed. The Vishnu Purana describes Dhruva as the steady pivot around which the stars and planets turn. This is why the word dhruv is used in Hindi for something permanent, as in dhruv satya, an "eternal truth". (Vishnu Purana 1.12.91)

2. The Maitri Upanishad: "the moving of the pole-star"

Yet one of our Upanishads boldly says that even Dhruva does not stay fixed. In the Maitri (Maitrayaniya) Upanishad 1.4, King Brihadratha gives up his kingdom and asks the sage Shakayanya about the meaning of life. To show that nothing in this world is permanent, he lists great changes in nature:

ध्रुवस्य प्रचलनं

dhruvasya pracalanam: "the moving of the pole-star"

"…there is the drying up of other great oceans, the falling of mountains, the moving of the pole-star, the cutting of the wind-ropes (that hold the stars), the submergence of the earth, and the departure of the gods from their place." Maitrayana Upanishad 1.4, translated by F. Max Müller (Sacred Books of the East, Vol. 15)

Read the full passage in Max Müller's translation.

A similar line also appears in the Maitreya Upanishad, where the king says the oceans dry up, mountains fall, and the position of Dhruva changes:

शोषणं महार्णवानां शिखरिणां प्रपतनं ध्रुवस्य प्रचलनं …

"Oceans dry up. Mountains sink down. The positions of Dhruva (the Polar Star) and of trees change." Maitreya Upanishad 1.2, from Thirty Minor Upanishads, tr. K. Narayanasvami Aiyar

What is this "moving pole-star" really?

Modern astronomy explains it. Earth's spin axis wobbles slowly like a spinning top, completing one circle in about 26,000 years. This is called precession. Because of it, the "pole star" changes over time: around 3000 BCE the star Thuban was near the pole, today it is Polaris, and in about 12,000 years it will be Vega. Some scholars believe this Upanishad line reflects an ancient observation of exactly this change.

Important difference: the Upanishad talks about the sky's pole (the celestial pole and the Pole Star). Today's news is about the magnetic pole of the Earth. They are two different things.

The common lesson: both ancient wisdom and modern science arrive at the same truth: even the things we think are fixed are actually moving. The rishis used the moving Dhruva to teach that the world is anitya (impermanent). Scientists today track the moving magnetic pole so that our planes and phones stay on course.

Quick summary

Earth has two North Poles: geographic (fixed) and magnetic (moving).
The magnetic North Pole has moved over 2,200 km since 1831 and is now closer to Siberia.
It sped up to about 50–55 km a year, but has recently slowed to about 35 km a year.
The cause is flowing liquid iron in Earth's outer core, not climate change.
The World Magnetic Model (WMM2025) keeps our navigation accurate until 2029.
The Vedas don't mention the magnetic pole, but the Maitri Upanishad famously mentions dhruvasya pracalanam, "the moving of the pole-star", as a lesson that nothing in nature is permanent.

Next time you open the compass on your phone, remember: "north" itself is on a slow journey.

Think about it

Why does a moving liquid metal core produce a magnetic field?
If the magnetic pole moves, why doesn't the geographic North Pole move with it?
What is the difference between the moving pole-star of the Upanishad and the moving magnetic pole?
