The weakening of the earth’s magnetic field.

There are reports from the European Space Agency(ESA) that the South Atlantic Anomaly is seeing the weakening of magnetic force up to 9% from the last 200 years. Covering the area from Africa to South America, the earth’s magnetic field is gradually weakening due to which satellites are experiencing technical disturbance.

Earth’s Magnetic field:

Earth’s magnetic field is important to sustain life. Its complex force protects us from harmful particles of sun and cosmic radiations.

It is generated by spinning liquid iron ocean which makes the core of earth around 3000 km down our feet. As a result, the Earth’s core acts as a conductor which creates currents and in turn generates an electric field.

According to recent studies, the position of the north pole is changing fastly. South Atlantic Anomaly is the area of weak magnetic field ranging from Africa to South America.

Effects:

The magnetic field not only protects us from harmful radiation but is also responsible for the navigation of many creatures like birds, turtles, etc. The magnetic field also plays an important role in the mapping functions of smartphones.

As a side effect, the navigation processes and smartphone’s mapping will be affected. It will cause issues for satellites and spacecraft especially in the south anomaly region.

The telecommunication also relies on it mainly and therefore computers, mobile phones, and many other devices will face difficulty. The south in a compass will point to north and north to south.

Reason behind weakening of magnetic field:

According to the researchers, there is no specific reason for the weakening of the magnetic field. Although it can be thought that poles will shift their position and plates are moving and this might be assumed to be the major reason behind this scarce.

Last time a geographical reversal took place was around 8 lakh years ago.

Scientists also say that because of COVID-9 the world is at a halt, and because of the reduction in human activities, the movement of the earth is also slowed down. And they believe that because of this they will be able to detect even the smallest convolutions happening in the earth.

Conclusion:

While all this weakening of the magnetic field’s act is not going to affect us largely but it can definitely cause serious problems to satellites, communication systems, and power systems as well.

There are mainly two outcomes to look after

  1. Geomagnetic reversal
  2. Geomagnetic excursion

and both these can cause a weakened magnetic field, and thus allowing more solar radiation to enter the earth’s surface.
