- The emergence of a mysterious area in the South Atlantic has led to speculation that Earth is heading towards a magnetic polarity reversal. Scientists mapped changes in the Earth’s magnetic field over the past 9,000 years & concluded that the magnetic North & South poles are unlikely to swap places https://www.lunduniversity.lu.se/article/earths-magnetic-poles-not-likely-flip-study 3 comments science

- Earth's magnetic north pole has been shifting south at speeds up to 30 miles per year recently. That's prompting some scientists to suggest we're on the brink of a geomagnetic reversal, where Earth's magnetic north and south poles swap places. Such a reversal hasn't happened for 780,000 years. https://astronomy.com/news/2021/09/when-north-goes-south-is-earths-magnetic-field-flipping 3348 comments science

- Scientists develop an energy-efficient strategy to reversibly change "spin orientation" or magnetization direction in magnetite at room temperature. This would let us create high-density spintronic memory devices with large capacity and even neuromorphic devices that mimic biological neural systems. https://www.tus.ac.jp/en/mediarelations/archive/20201117_8877.html 7 comments science
- Earth’s magnetic field is mysteriously weakening, causing satellites and spacecraft to One possibility, according to the ESA, is that the weakening field is a sign that the Earth's magnetic field is about to reverse, whereby the North Pole and South Pole switch places. https://www.independent.co.uk/life-style/gadgets-and-tech/news/earth-magnetic-field-satellites-space-a9528571.html 7 comments worldnews
- Earth's most recent magnetic field reversal, some 770,000 years ago, took at least 22,000 years to complete. That's several times longer than previously thought, and the results further call into question controversial findings that some reversals could occur within a human lifetime. https://www.smithsonianmag.com/science-nature/earths-magnetic-field-could-take-longer-flip-previously-thought-180972843/ 4 comments science
- Earth's roaming magnetic poles create longer periods of instability. In a new study, researchers discovered that the last field reversal took 22,000 years to complete -- Although some believe reversals could happen over the course of a human life, the findings don't support that theory. https://edition.cnn.com/2019/08/07/world/earth-magnetic-field-reversal-scn/ 5 comments science
