Earth’s magnetic field weakened by 9%
(ORDO NEWS) — According to the latest findings of scientists, the magnetic field of our planet is weakening. This is especially noticeable in the area from Africa to South America. Changes negatively affect the equipment of scientists: there have already been failures in the work of some near-Earth devices.
The magnetic field is the shield of the Earth, so its weakening will make our planet defenseless against cosmic radiation and the solar wind, which consists of charged solar particles. A magnetic field is formed from molten iron in the outer core.
The substance is located at a depth of 3 thousand kilometers.
Scientists have long discovered that a magnetic field is an unstable phenomenon. Throughout the history of the Earth, the North and South poles have shifted at least several times. The poles are able to change only their position, but also power.
Over the past two centuries, the magnetic field has lost 9% of its power, and a region of reduced strength has been formed between Africa and South America. Scientists have called it the South Atlantic Anomaly.
According to new research, there is a second area of minimal activity in southwestern Africa. Perhaps this is a divided South Atlantic anomaly.
A change in the magnetic field will not affect living creatures and equipment on the surface of the planet, a negative effect is manifested only on satellites. Scientists are faced with many technical problems.
Weakening of the magnetic field has been known for a long time, but scientists to this day cannot find out why this is happening. Maybe this is due to another change in the North and South poles (this happens once every 250 thousand years). Specialists continue to study satellite data and draw conclusions. Perhaps the situation will clear up over time.
