Magnetic field is in a permanent state of flux. Magnetic north wanders, andevery few hundred thousand years the polarity flips so that a compass would point south instead of north. Moreover, the strength of the magnetic field constantly changes - and it is currently showing signs of significant weakening. (ESA)
Measurements made by Swarm over the past six months confirm the general trend of the field's weakening, with the most dramatic declines over the Western Hemisphere. But in other areas, such as the southern Indian Ocean, the magnetic field has strengthened since January.
The field is particularly weak over the South Atlantic Ocean - known as the South Atlantic Anomaly and the latest measurements confirm the movement of magnetic North towards Siberia.
Comment: Actual measurements of the intensity of the total geomagnetic field began in Gauss's observatories in 1840. Since then, its intensity has been continually decreasing at a rate of 6.3% per century. At this rate the intensity of the field will reach 0 in 1,600 years. This trend has been confirmed by studies of the magnetization in ancient clay pots, showing that the Earth's magnetic field was approximately twice as strong in Roman times.
