North Magnetic Pole Moving East Due to Core Flux

[Neoxter]

Earth's north magnetic pole is racing toward Russia at almost 40 miles (64 kilometers) a year due to magnetic changes in the planet's core, new research says.

The core is too deep for scientists to directly detect its magnetic field. But researchers can infer the field's movements by tracking how Earth's magnetic field has been changing at the surface and in space.

Now, newly analyzed data suggest that there's a region of rapidly changing magnetism on the core's surface, possibly being created by a mysterious "plume" of magnetism arising from deeper in the core.

And it's this region that could be pulling the magnetic pole away from its long-time location in northern Canada, said Arnaud Chulliat, a geophysicist at the Institut de Physique du Globe de Paris in France.

Finding North

Magnetic north, which is the place where compass needles actually point, is near but not exactly in the same place as the geographic North Pole. Right now, magnetic north is close to Canada's Ellesmere Island.

Navigators have used magnetic north for centuries to orient themselves when they're far from recognizable landmarks.

Although global positioning systems have largely replaced such traditional techniques, many people still find compasses useful for getting around underwater and underground where GPS satellites can't communicate.

The magnetic north pole had moved little from the time scientists first located it in 1831. Then in 1904, the pole began shifting northeastward at a steady pace of about 9 miles (15 kilometers) a year.

In 1989 it sped up again, and in 2007 scientists confirmed that the pole is now galloping toward Siberia at 34 to 37 miles (55 to 60 kilometers) a year.

A rapidly shifting magnetic pole means that magnetic-field maps need to be updated more often to allow compass users to make the crucial adjustment from magnetic north to true North.

Wandering Pole

Geologists think Earth has a magnetic field because the core is made up of a solid iron center surrounded by rapidly spinning liquid rock. This creates a "dynamo" that drives our magnetic field.



Scientists had long suspected that, since the molten core is constantly moving, changes in its magnetism might be affecting the surface location of magnetic north.

Although the new research seems to back up this idea, Chulliat is not ready to say whether magnetic north will eventually cross into Russia.

"It's too difficult to forecast," Chulliat said.

Also, nobody knows when another change in the core might pop up elsewhere, sending magnetic north wandering in a new direction.

40 miles a year !!! that's too much !
is "Global Warming" related to this ?

[Neoxter]

I don't think so, the global warming deals with atmosphere while the magnetic field basically related to the earth's crust and what's beneath.

This shifting is normal, it happens yearly and since long time ago..but the weird thing I'm waiting for is the polar shift and reversal that what research say it will happen in 2012, which is one of the major reasons of the whole 2012 hoax.

A polar shift and reversal ya3ne the north pole and the south pole will shift magnetically.

It's here, we are doomed people, judgment day is near... Prepare to die, or get the hell out of this planet

The earth has been alive for billions of years, this is a very normal activity, like it is said in the article, the north pole have been shifting ever since the scientists first located its, the speed is not much of an issue, because, like I said, the earth have been alive for billions of years, of course this activity happened before on an even faster rate than 40 mpy.

let us wait till 2012 w mna3ref
or lets wait michel hayek and mike feghaly on new years eve

[Confucius]

*clap* heh thanks Neo this is nice..anw can u find something "useful" explaining the whole 2012 commotion?

[Neoxter]

ur welcome!

what do u mean? explanation abt the 2012 whole thing? i guess there is an old thread in the forum abt it. Or explanation abt the pole shifting in 2012?

[Confucius]

explanation aboot the pole shifting in 2012 yep
