The South Atlantic Anomaly is also of interest to NASA's Earth scientists who monitor the changes in magnetic strength there, both for how such changes affect Earth's atmosphere and as an indicator of what's happening to Earth's magnetic fields, deep inside the globe. Credits: NASA's Goddard Space Flight Center . Notice, also, how fast the magnetic field recovers after it reaches 'zero', in some cases much less than 10,000 years. Presently, Earth's magnetic field is weakening in strength by 5% every 100 years. It may be near zero in another few thousand years at this rate NASA says Earth's magnetic field weakening, splitting into two lobes.

Earth's Magnetic Field Is WEAKENING. Over the past 200 years, the intensity of the geomagnetic field has decreased by 9%. This has happened more than once in the history of the Earth, but this should not comfort us. The fall in the geomagnetic field is a sign of a planetary catastrophe: a change in the Earth's magnetic poles A geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged (not to be confused with geographic north and geographic south).The Earth's field has alternated between periods of normal polarity, in which the predominant direction of the field was the same as the present direction, and reverse polarity, in which it. At the prresent time, Earth's magnetic field is weakening in strength by 5% every 100 years. It may be near zero in another few thousand years at this rate. The figure above, however, shows that Earth's field often changes its strength significantly in a short time (measured in thousands of years) and often does not vanish everytime

This immense, creating wonder, called the South Atlantic Anomaly, has charmed and concerned researchers for a considerable length of time, and maybe none [ So the prospect of that field weakening, which it does when it's getting ready to flip, is worrisome: It would leave us without sufficient protection. The Earth's North magnetic pole has been wandering at 10-year intervals from 1970 to 2020, as seen in this animation from the National Centers for Environmental Information The weakening of magnetic field gives rise to speculations that Earth is heading for an eminent pole reversal, a phenomenon in which north and south poles switch places. According to the data given by the ESA, the magnetic field has lost nearly nine per cent of its strength on a global average in the last 200 years The magnetic field of Earth is constantly changing. And, at the moment, even more rapidly than previously thought - up to 10 times, as British researchers have now figured out.
