Earth’s Magnetic Field is Weakening and might Reverse in the Future

Browse By

Satellite data from the European Space Agency (ESA) shows that the mysterious “South Atlantic Anomaly” (an ‘area’ of reduced intensity in Earth’s magnetic field, extending all the way from South America to southwest Africa) continues to grow and the observations show that we may deal some strange phenomena in future.

The ESA scientists also report that in the past five years, the anomaly have split in half, one area of magnetic weakness over the southwest of Africa and the other one to the east of South America.

There is really nothing to be afraid of at present. The most significant effects right now are limited to technical malfunctions on board satellites and spacecrafts, which can be exposed to a greater amount of charged particles in low-Earth orbit as they pass through the region between South America and the South Atlantic Ocean.

Actually, in the last 200 years, Earth’s magnetic field has lost about 9 percent of its strength on average assisted by a drop from approximately 24 micro-teslas to 22 micro-teslas in the South Atlantic Anomaly over the past 50 years. Why this is happening is still not clear.

Researches show that the Earth’s magnetic field flips with north and south pole swapping places in every few hundred thousand years. But, really, magnetic field reversals don’t take place in a day! Even if things are headed towards the North Pole and the South Pole swapping places, you probably wouldn’t want to be around to witness it!
