The Earth's magnetic north pole is moving to Russia to almost 40 miles (64 kilometers) per year due changes in the magnetic core of the planet, according to results of a new search. The core is too deep for scientists to directly detect its magnetic field. But the researchers can deduce the movements of the field by registering as a change in Earth's magnetic field at the surface and space.
Now, just analyzed the data suggest that there is a region of magnetism on the surface of the center, perhaps created by a mysterious "flow" of magnetism arising from the depths of the nucleus, rapidly changing. "And it is this region that might be responsible for moving the magnetic pole position away from the natural long-time in northern Canada, "said Arnaud Chulliat, a geophysicist at the Institut de Physique du Globe de Paris in France. The magnetic north, which is where the compass needles point effect, it is close but not exactly the same place as the geographic North Pole. Currently, magnetic north is close to Ellesmere Island in Canada. The Navigators have used for centuries to the magnetic North orientation. Although global positioning systems have largely replaced these traditional techniques, many people still use the compass to move underwater, or where you are not able to communicate with the GPS satellites. The North Magnetic Pole has moved little since the place discovered by scientists in 1831. Then in 1904, Polo began moving northeast at a steady pace of about 9 miles (15 kilometers) per year. In 1989 there was an acceleration, and in 2007 the scientists confirmed that the Pole is now galloping toward Siberia at 34.37 miles (55.60 kilometers) to the 'year. The earth has a magnetic field because the core is a solid iron center surrounded by spinning liquid metal. This will create a "dynamo" that guides our magnetic field. Scientists suspect that as the molten core is constantly moving, changes in its magnetism might be related to the position of the surface of magnetic north. Although the new research seems to back up this idea, Chulliat not ready to say whether the North then the magnetic cross Russia. "It's too hard to predict," said Chulliat.
PS This news could be of interest for meteorological studies, as a shift of the magnetic pole and the relevant law, could lead to disruption of our planet, and even solar activity may play a role.
