Earth's magnetic field has been weakening to 10 times faster - VIDEO PDF Print E-mail

Scientists from the European Space Agency (ESA) said that, according to the magnetic field of our planet began to weaken with extraordinary speed. The measurements made by the satellite Swarm, consisting of three spacecraft indicate that now, the field is attenuated by 10 times faster than normal.

Earth's magnetic field is a huge bubble, which, though invisible to the naked eye, plays an important role in protecting the Earth from the merciless Sun radiation.

The magnetic field exists, since the Earth has a huge iron core surrounded by an outer layer of molten metal. Changes in core temperature and the Earth's rotation agitates the outer bark, creating lines of magnetic force.

Movement of the molten metal are the reason that some areas of the magnetic field are enhanced while others are attenuated.



According to scientists, Earth's magnetic field extends over a distance of about 600 000 km, and is constantly subject to change. However, researchers are puzzled by how quickly these changes began to occur in our time.

Previously, the magnetic field is weakened by about 5 percent per century. Now, the figure is 5 per cent per decade.

In addition, the data suggest that the weakest point is the Western Hemisphere, while other areas, including the southern part of the Indian Ocean, intensified.

Scientists at ESA believes that the weakening of Earth's magnetic field due to the fact that the Earth's magnetic poles are ready to change as a result of changes in the Earth's core.

It is believed that the magnetic north pole shifted to Siberia, and then move further.

However, such a change of the magnetic poles have already occurred many times throughout history, so researchers claim that there is no cause for concern. This change does not occur immediately, but may take several hundreds, and perhaps thoUSAnds of years.

There is no evidence that it can lead to the apocalypse. During the last shift of the magnetic poles are not observed mass extinction or damage of radiation. Most may suffer electrical and communication systems.
