Earth magnetic field strength by location
WebApr 11, 2024 · The magnetic field of the Earth is similar to that of a bar magnet, with a north and south magnetic pole. However, the Earth's magnetic poles are not fixed and can vary in position and strength over time. In fact, the magnetic field has been found to reverse its polarity on average every 200,000 to 300,000 years, with the last reversal ... WebDec 7, 2024 · In the Atlantic Ocean between South America and Africa, there is a vast region of Earth’s magnetic field that is about three times weaker than the field strength at the poles. This is called the South Atlantic Anomaly (SAA), and it’s the focus of the CoreSat project being led by Professor Chris Finlay from the Technical University of ...
