The Earth's magnetic field is slowly weakening between Africa and South America, causing technical disturbances in some of the satellites, scientists at the European Space Agency observe. They say that the current drop in intensity is within normal fluctuation levels. The Earth's North Magnetic Pole has also moved away from Canada towards Siberia in Russia in recent years. Scientists say that this pole will continue to move towards Russia, but with time it will start to grow slowly. With this at top speed, it is making 50-60 km a year. In the last 200 years, the electromagnetic field around the Earth has lost about nine percent of its strength. Between 1970 and 2020, the Earth's magnetic field has weakened considerably in the region extending from Africa to South America, known as the 'South Atlantic Anomaly'. The region has moved westward at a rate of about 20 km per year. The German Research Center for Geosyncs said in a statement, "The new, eastern minimum of the South Atlantic anomaly has appeared in the last decade and more recently Strictly evolving over the years. Whereas "Earth's magnetic field, or geomagnetic field, is a magnetic field that exits a force on charged particles emanating from the Earth's interior. It spreads in the shape of a comet with a tail of magnetism that extends millions of miles of the Earth, opposite to the Sun.
The Earth's magnetic field is due to the planet's metal and liquid outer core about 3,000 km below our feet. It creates electric currents that generate and change our electromagnetic fields. The outer core of the planet is like a giant dynamo. The rotation of the Earth creates a stir inside the liquid outer core that gives rise to a geomagnetic field. A compass describes the way the Earth works due to its magnetic field. Also, the northern lights in polar regions of the Earth The magnetic field is also caused - the energy particles emitted by the sun are transmitted to the poles by the Earth's magnetic field, where they combine with the atmosphere to form aurora borealis. At the same time, the Earth's magnetic field protects the life of the Earth from harmful cosmic radiation and charged particles emitted from the Sun. Birds, turtles and other creatures also use the Earth's magnetic field to navigate. In fact, mapping functions in navigation systems and smartphones can be affected. Between Africa and South America, the weakening of the Earth's magnetic field is causing issues for satellites and spacecraft. Telecommunication and satellite systems also depend on the geomagnetic field. Therefore, computers, mobile phones and other devices may also face difficulties. Compass may point south to Canada and north to Antarctica.
The European Space Agency's swarm of satellites, which identify and measure the various magnetic signals that constitute the Earth's magnetic field, is studying the evolution of the South Atlantic anomaly. The challenge lies ahead to study the reason behind the change. A team at Leeds University stated that the drift of the North Pole is explained by the competition of two magnetic "blobs" at the edge of the Earth's outer core. Changes in the flow of molten material into the interior of the Earth have altered the strength of negative magnetic flux. "This change in the pattern of flow has weakened the patch under Canada and ever slightly increased the strength of the patch under Siberia Has increased. That's why the North Pole has given up its historic position on the Canadian Arctic and crossed the international dateline. Dr Phil Livermore told BBC News, "North Russia 'war if you want. Ka raga 'is winning. "Another possible reason according to ESA could be that the Earth's magnetic field is reversing ie the north and south poles can switch. Such geomagnetic reversals occur every 2,50,000 years and it was longer than it had been in the past 7,80,000 years ago. However, a study published in 2018 in the scientific journal Proceedings of the National Academy of Sciences found that despite the weakened field, "the Earth's magnetic field might have reversed." The reversal of a magnetic field takes thousands of years, the geomagnetic The true reason for the weakening of the earth's region is yet to find out another one of the mysteries of the Earth.
