Earth's Magnetic North Pole Officially Has A New Position

Hping to keep tabs on the magnetic north's wandering ways, the World Magnetic Model 2025 has been released this week, revealing the latest official predicted placement of Earth's magnetic fields. This version will remain valid until late 2029, during which time we can expect to see the magnetic north pole slowly edge further toward Russia.

The new version is of timely importance too as the magnetic north pole’s movement seems to be accelerating.

Since the 1830s, the north magnetic pole of Earth has relocated some 2,250 kilometers (1,400 miles) across the upper stretches of the Northern Hemisphere from Canada towards Siberia. Between 1990 and 2005, the rate of pole movement increased from less than 15 kilometers (9.3 miles) per year to around 50 to 60 kilometers (31 to 37 miles) per year.

“The current behaviour of magnetic north is something that we have never observed before. Magnetic north has been moving slowly around Canada since the 1500s but, in the past 20 years, it accelerated towards Siberia, increasing in speed every year until about five years ago, when it suddenly decelerated from 50 to 35 km per year, which is the biggest deceleration in speed we’ve ever seen,” added Dr Brown.

Lots of work there. Thank you for the list.

1. The map up above only shows the North Magnetic Pole movement up to 2020. Not the latest position for 2025 that is mentioned in the article.

2. Oddly, the South Magnetic Pole has not moved ant appreciable amount over the same period.

MARTY! DO YOU KNOW WHAT THAT MEANS?????...............

Interesting.

The effect (of this movement of the North Magnetic Pole) depends on the latitude of the runway, but more important on the longitude of the runway.

Note too that the amount of the change on on far the runway is from the North Magnetic Pole: Properly, the plane’s (or ship’s)
Magnetic compass needle is aligning on the Magnetic field stretching from the South Magnetic Pole, across the Equatir, to the North Magnetic Pole. So, since the Sourh Magnetic Pole has near-zero movement, and the NorthvMagnetic Pile is moving in a straight line towards Russia’s Siberian coast, if your runway is in the Eastern Time Zone of the USA, there is no change at all!

If you are further north and east, say Norway or Murmansk Russia, the your Magnetic compass shows a massive swing of almost 20 degrees correction in only 50 years.

If you are further west and north, say the North coast of Alaska, your compass correction is opposite of Norway’s change, but also 20 to 30 degrees.

South of the equator, but at the same longitude as Alaska? Near zero change.

Since the South Magnetic pole is nearly stationary, Then they should make compasses that point to the South Pole........................ 🙄

When the Earth hits 88mph something’s going to happen?

[Vaduz]

Good point it always moves.

[snip] The south magnetic pole is constantly shifting due to changes in Earth's magnetic field. As of 2005 it was calculated to lie at 64°31′48″S 137°51′36″E,[2] placing it off the coast of Antarctica, between Adélie Land and Wilkes Land. In 2015 it lay at 64.28°S 136.59°E (est).[3] That point lies outside the Antarctic Circle. Due to polar drift, the pole is moving northwest by about 10 to 15 kilometres (6 to 9 mi) per year. Its current distance from the actual Geographic South Pole is approximately 2,860 km (1,780 mi).[1] The nearest permanent science station is Dumont d'Urville Station. While the north magnetic pole began wandering very quickly in the mid 1990s, the movement of the south magnetic pole did not show a matching change of speed. [/snip]

Now it’s headed to Russia! What will we do if the Russians get it? Will Santa Claus defect?

[Sirius Lee]

It changes constantly and always has.

I have never been angrier in my life.

[Vaduz]

Will Santa Claus defect?

Yes his GPS is fool proof.

"...Since the magnetic poles are constantly moving, albeit very slowly, the NOAA and the British Geological Survey (BGS) have to regularly revise their models...."

In other words, this means there's nothing new to report (because the magnetic pole moves constantly) except that it finally moved enough that some bureaucrats could be bothered to record the change.

There is a periodic 90 degree rotation that occurs.

My understanding was that the Earth - currently a magnetic dipole - will, over centuries, transform into a quadrapole, then a 16-pole, etc. Eventually, the process halts - maybe around the time the Earth has 512 North Poles and 512 South Poles, and the Earth's greatly attenuated magnetosphere is at its weakest - and then reverses.

At the end of the cycle, the Earth is again a dipole, but with the new magnetic North Pole roughly in Antarctica, and the new magnetic South Pole somewhere in the Arctic Ocean.

The observed gradual geographic drift of the Poles is a separate issue.

Correct me if remember that incorrectly!

Ben Davidson has a set of videos around the 12,000 year disaster cycle. His work is usually well supported with peer reviewed papers. Another author, Robert Felix, wrote Not by Fire, but By Ice. He identifies multiple geophysical cycles that cause calamities for Earth and makes a good argument that a large number of them are converging for a repeat performance.
