Earths magnetic field. Clear, or not?

The change of the magnetic poles is a clip supposed causes of doom, which is expected December 21, 2012-year.

Science today is powerless to give a precise answer, as far as possible a sharp reversal, however, scientists continue to explore this natural phenomenon.

 

French researchers from the University of Paris VII Denis Diderot name found that the change of the magnetic poles may occur at any time. In their view, can only predict the polarity of 10-20 years. More long-term and accurate prediction impossible.

The inversion of the magnetic poles of the Earth, which has been marked in the past, followed by a brief disappearance of the magnetosphere. For Earth's biosphere means thinning of the ozone layer and the disappearance of the protection from the solar wind and cosmic radiation. If the "reversal" will end soon, life on our planet can survive, but if the land will be left without a magnetic field for several years, it will mean the death of all life, writes sunhome.ru

Now the magnetic field of the earth is falling. Over the last 22 years of Earth's magnetic field was weaker by 1.7%, and in some parts of the Atlantic Ocean, it has weakened by 10%, and in several regions of slightly increased.

Displacement of the magnetic poles of the Earth was registered in 1885. Since then, the south magnetic pole has shifted to 900 km in the Indian Ocean, and the magnetic north — toward the East Siberian magnetic anomaly. The drift velocity of the poles is now about 60 miles per year, which has never previously been observed.

Earth's magnetic poles

Magnetic Pole — A common point on the earth's surface, where the Earth's magnetic field is directed strictly at 90 ° to the surface.

North Magnetic Pole

Movement of the north magnetic pole of the Earth since the beginning of XVII century.

The location of the north magnetic pole does not coincide with the geographic north pole. From about the beginning of XVII century the pole is located at the borders of pack ice in the Canadian Arctic today. This leads to the fact that the compass needle points to the north is not exactly, but only approximately. Every day the pole moves in an elliptical path, and, in addition, is shifted to the north and north-west at a speed of about 10 km per year, so any of its coordinates are temporary and uncertain. Since the second half of the twentieth century, the pole is moving quickly in the direction of Taimyr. In 2009, the rate of movement of the north magnetic pole was 64 kilometers per year.

As stated in 2005 in Ottawa, the Canadian head of Geomagnetic Laboratory of Natural Resources Larry Nyuitt, the north magnetic pole of the Earth, at least 400 years "belong" to Canada, "left" to the country. Has the ability to move a magnetic pole, about the beginning of the seventeenth century, is located under the pack ice in the borders of the current Canadian Arctic, is outside the 200-mile limit of Canada.

South magnetic pole

The location of the south magnetic pole does not coincide with the geographic south pole. Currently, he is on the edge of Antarctica.

Polarity

Traditionally, the end of the magnet, indicating the direction to the north is called the north pole of the magnet, and the other end — the south. We know, however, that like poles repel, rather than attract. This implies that the geographic north magnetic pole is pointed north (blue) part of the compass, from the physical point of view is to the south. As noted above, the difference between the geographic north pole and the magnetic north pole of the Earth is negligible. Therefore, with a certain error can be argued that the blue part of the compass needle points to the north (meaning the geographical north magnetic pole and the north pole of the Earth).

Geomagnetic Pole

Geomagnetic Pole is a point where the magnetic dipole axis (which is the main component of the expansion of Earth's magnetic field in multipoles) intersects the surface of the Earth. Since the magnetic dipole is only an approximate model of the magnetic field of the Earth, the geomagnetic pole differ within a given distance from the true magnetic poles where the magnetic inclination is 90 °.

In 1831, the British polar explorer John Ross in the Canadian Archipelago was discovered the magnetic north — the area where the magnetic needle vertical position, that is, the inclination is 90 °. In 1841, James Ross (nephew of John Ross) reached the south magnetic pole of the Earth is in Antarctica.
