Experts said that the Earth’s magnetic field will become weaker and more complex in form if a reversal occurs. It is also predicted that the strength of the magnetic field will decrease by 10 percent compared to its present state. Furthermore, it may also lead to the swapping or even the existence of many of north and south magnetic poles.

The Earth’s magnetic field serves as a protection against harmful solar radiation. As an invisible force field, it deflects and drives charged particles from our planet. This field continues to evolve as time goes by. Based on the length of our planet’s existence, we could have had “several hundred global magnetic reversals.”

On the average, the transpiration of geomagnetic reversals occur a few times every million years, with an irregular interval of up to tens of millions of years.Experts also defined “events and excursions,” a phenomenon characterized by incomplete reversals wherein the magnetic poles veer away from the geographic poles. It can also cross the equator before returning to its point of origin.

IFLScience reported that the last full reversal occurred around 780,000 years ago in the Brunhes-Matuyama. The Laschamp event, another temporary reversal, transpired around 41,000 years ago. The reversal was said to have lasted 1,000 years as the actual polarity shift lasted around 250 years.

If the magnetic field deteriorates, heightened levels of radiation may alter on and within the Earth’s surface. This will accelerate the charged particles that may be detrimental to the risks of satelittes, ground-based electrical infrastructure and aviation.

Earthsky warned that our planet is at the verge of magnetic field shift. Geophycisits have also warned that the magnetic field of our planet has tremendously weakened for the past 160 years. The collapse is centered within the southern hemisphere known as South Atlantic Anomaly.
