Earth magnetic field weakening NASA

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 During the next 150,000 years it rose to a maximum strength and then began to decline. 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. A small but evolving dent in Earth's magnetic field can cause big headaches for satellites.

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
