Scientists intrigued by the atypical behavior of the Earth's magnetic field A movement with unexpected characteristics in the magnetism of the Earth intrigues the scientists of the world.

The magnetic field of our planet behaves unexpectedly – and leaves scientists in the world intrigued. The scenario is so unexpected that it causes the update of existing magnetic field description models, reports the "UOL"

. This change forces geomagnetism experts to update the global magnetic model . ] a kind of map describing the magnetic field in space and time

What is the Earth's magnetic field?

Because of its liquid metal core, Earth functions as a huge magnet with positive and negative poles. The magnetic field is a "layer" of forces around the planet between these two poles.

Known as magnetosphere this great layer is extremely important for terrestrial life.

Geologist ] Ricardo Ferreira Trindade researcher at the Institute of Astronomy and Geophysics of the University of São Paulo (USP), explains to "UOL":

This is the magnetic field that protects us from the particles coming from the outside, in particular the wind (which can be very harmful).

The essential magnetic field is generated by the movement of liquid metals constituting the center of the planet. According to the USP researcher, the problem is that he has "varied in a very different way over the last ten years".

According to the USP researcher, much faster speed than previously varied. "

The North Pole is constantly changing its magnetic position, but still within limits.Although the direction of these changes is unpredictable, the speed was previously constant.

However, planetary history shows us that the Earth's magnetic field is so variable that the North Pole and the South Magnetic Pole have already been inverted several times since the formation of the planet.

Its current configuration is identical to that of 700,000 years ago, but it can begin to be reversed at any time.

According to Marcia Ernesto also a researcher at the Institute of Astronomy and Geophysics of the University of São Paulo (USP), this inversion would take about a thousand years. "in the field) means that it is heading for an inversion, but that is not certain.This could only be a momentary acceleration," adds the specialist.
