![]() ![]() Of all the places on Earth, the area where the planet's magnetic field is at its weakest, dubbed as the South Atlantic Anomaly, sits in between Chile and Zimbabwe.Īnother Rochester professor, Eric Blackman, believes that the South Atlantic Anomaly is the birthplace of the most recent pole reversal, and it will continue to be the site of a magnetic pole flip in the future. However, current data reveals that the strength of the planet's magnetic field has been weakening faster than expected. ![]() ![]() The last time that the Earth's magnetic fields switched was 800,000 years ago. It also plays a significant role in protecting the Earth from radiation in space. The study on the magnetic field of the planet is essential not just because of locating places using the needle points of the compass. "We've known for quite some time that the magnetic field has been changing, but we didn't really know if this was unusual for this region on a longer timescale, or whether it was normal." The lead author of the study published in the Geophysical Research Letters, Vincent Hare, explained what's happening in the area they have been studying. A study by the University of Rochester looked at southern Africa where they observed what is being called the South Atlantic Anomaly. News of how the Earth's magnetic field might flip has stirred controversy in the past few months.
