It took 250 years for the Laschamps reversal to take place and it stayed in the unusual orientation for about 440 years. At ...

A magnetic observatory is being re-established on South Georgia to provide vital data on the 'South Atlantic Anomaly' as scientists monitor a possible reversal of the earth's magnetic field.

The South Atlantic Anomaly is an area where Earth’s  magnetic field is weaker, resulting in increased radiation exposure.
