The Earth’s magnetic field is due to the iron core and liquid outer core of the planet lying 3,000 KM below. It is observed that the magnetic field is weakening between Africa and South America which is leading to technical disturbance in satellites. As it’s affecting satellites which helps us in day to day communication can cause fluctuation in the network.
In the last 200 years, the earth’s magnetic field has decreased about 9 percent. Earth’s magnetic field plays an important role in not only for communication and protection purposes but also serves as a deflect to the solar winds which try to pass through the ozone layer.In short, it prevents the UV radiation.
The magnetosphere is the sphere above the ionosphere. According to an archive of New York Times, the earth’s weakened magnetic field is responsible for entry of harmful UV rays in the atmosphere. The space agencies can face interruptions in space missions, which can cause higher levels of radiation during magnetic storms. The weakening of the geomagnetic field can have an effect on electricity-based appliances. Hence, the Earth’s geomagnetic field has no effect on human beings but has an effect on their lifestyle on the basis of technology. Magnetic storms, one of its causes can lead to distortion of communication systems thus affecting the global positioning system(GPS).
The earth’s magnetic field is generated by turbulence in the core. All in all, the process is like an electric generator where the convection kinetic energy is converted into electric energy. There is a question arising that, “Are we going to face magnetic reversal?”, the answer is no. As decrease is observed in the magnetic intensity that doesn’t indicate any magnetic reversal. Scientists have discovered that our brain can sense the magnetic intensity change. The gradual weakening of the magnetic field is a bane for some migratory birds which can cause disturbance in their path as this affects the navigation system too.
The major blunder is that it will affect internet efficiency. The spacecraft may face some technical issues. The spacecraft moves with the help of magnetic field with the force of “Lorentz Force”. The news reports also claim that flow of molten lava in the core of the earth can also affect the negative magnetic flux.
As there are no magnetic flips so there is no reverse in the magnetic field of the earth. The European Space Agency is still studying about the South Atlantic Anomaly.
WHAT IS SOUTH ATLANTIC ANOMALY?
According to wikipedia, South Atlantic Anomaly(SAA) is an area where the Earth’s
inner Vallen radiation belt comes closest to the earth surface, meaning it corresponds
to the dipolar magnetic fields at ionospheric level.However, the field itself varies as an intensity gradient.
CAN THIS WEAKENING AFFECT OCEANS?
Electrical charges present in the water bodies are basically ions of sodium and chlorine transported with the ocean flow are deflected by earth’s magnetic field. The molten cores,rock and upper mantle of streams of charged particles called solar winds. If the particles weren’t deflected by a magnetic field,it can cause the navigation system to jumble.
