The Earth’s magnetic field continues to weaken and raises scientists’ concern:: El Litoral – News – Santa Fe – Argentina

The magnetic field that surrounds the Earth and protects it, among other things, from solar radiation is gradually weakening and is causing concern in the scientific field.

It has already lost about 9% of its strength. The Earth’s magnetic field continues to weaken and causes concern to scientists. The magnetic field that surrounds the Earth and protects it, among other things, from solar radiation is gradually weakening and generates concern in the scientific field.

Earth’s magnetic field enables life on the planet by deflecting the solar wind, preventing erosion of the atmosphere and bombardment of the surface by high-energy radiation. It is this field that prevents our planet from being cold and parched.

On the other hand, this magnetic field evolves and undergoes changes. There are periods of greater or less intensity and the magnetic poles change their position, as well as, on occasions, reverse.

The latest observations indicate that the magnetic north pole is moving in the direction of Siberia, at a speed of about 40 kilometers per year.

In the past 200 years, the magnetic field has lost about 9% of its strength on a global average. Much of this loss occurred between Africa and South America and is known as the South Atlantic Anomaly.

This behavior has geophysicists baffled and is causing technical disruptions to the satellites orbiting Earth. Scientists are using data from the ESA (European Space Agency) Swarm constellation to improve understanding of this area.

The importance of the magnetic field

It is a complex and dynamic force that protects us from cosmic radiation and charged particles from the Sun, making it essential for life on Earth.

The magnetic field is largely generated by an ocean of superheated spiraling liquid iron that forms the outer core about 3,000 km below our feet. Acting as a rotating conductor on a bicycle dynamo, it creates electric currents, which in turn generate our constantly changing electromagnetic field.
