Magnetic north pole is shifting eastwards 40 miles a year

Today I read a news in Mumbai Samachar (Gujarati daily) saying Mangetic North Pole is rapidly advancing eastwards - towards Russia - at about 40 miles (68 kms) a year. Interesting!

Then I came across a 24 Dec 2009 daily news in National Geographic, which is the source of this news item. The article says following:

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 metal. 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.


It's predicted that magnetic north and south poles will be reversed, but not in near future. Well, process of magnetic pole reversal has accelerated now.
