North Magnetic Pole Moving East Due to Core Flux
National Geographic ^ | December 28, 2009 | Richard A. Lovett

Posted on 12/28/2009 4:21:56 PM PST by NYer

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.

(Get more facts about Earth's insides.)

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.

Chulliat presented his work this week at a meeting of the American Geophysical Union in San Francisco.

The new 'clarion call' for global warming?

It’s probably just trying to get away from Zero’s Healthcare plans.

There’s no question this poses a danger to humanity over the long run, and we need to tax all activities that’s leading to changes in the earth’s flux.

The magnetic North is always moving. When I have to use map coordinates from a map made in the 1860's, I have to adjust for the change the North has made.

Ahh... just drop a nuke down that volcano in Alaska... that should fix it.

I can’t believe Algore and his band of Enviroloonies aren’t doing anything about this! We’re all going to die!

It’s because the magnetic polar bears are dying. Oh, wait, they aren’t.

Moving about five inches per minute; an inch every 12 seconds.
