Accurately recorded the last magnetic pole switch of the earth, this switch was created as a fresh flip, and it’s long over time now — RT World News



Throughout the history of the earth, the magnetic poles of the earth have undergone several violent flips. Another change that should have been made long ago is that scientists have created the most detailed conversion record to date.

This sounds incredible, but the poles of the earth usually reverse every 200,000 to 300,000 years. However, there has been no change since about 750,000 years, and experts warn that this has been too long.

Scientists warn that unexplainable anomalies that weaken the Earth’s magnetic field are evolving and splitting


The magnetic field is charged by the outer layer of molten metal on the earth. It is vital to life on our planet, it plays a key role in the navigation system, and it also provides protection from outer space radiation.

About 40,000 years ago, it tried to switch and then fix it back in place. This NASA illustration captures the huge destruction of the field during a reversal:

We know very little about the effects of this flip, except that once completed, the needle on the compass will tell us that North is South and South is North. The latest research has given people a better understanding of the geophysical events that led to change and how our planet responded after a disaster.

This research was conducted by scientists from the National Institute of Polar Research (NIPR) in Japan. The results showed that the magnetic field became unstable at least 10,000 years before the last change of direction actually took place, and the entire reversal process took at least 20,000 years to complete.

The research team came to their conclusions after collecting a large number of samples and conducting ancient rock magnetic analysis. Yuki Haneda, project researcher at NIPR, said: “Our data is one of the most detailed paleomagnetic records during the Matuyama-Brunhes geomagnetic reversal period, providing a deep insight into the mechanism of geomagnetic reversal.”

Now, Coffin plans to study how the geomagnetic reversal affects plankton and plants by studying marine microfossils and pollen data collected in samples.
