Magnetic North Pole's Rapid Shift Towards Russia Baffles Scientists

The Earth's North Magnetic Pole is shifting towards Russia at an unprecedented rate, posing potential risks to modern navigation systems reliant on magnetic orientation, such as smartphones and GPS devices. This rapid movement, now at 25 km/year, is linked to changes in Earth's outer core dynamics and solar activity, raising concerns about a possible pole reversal. Efforts to mitigate risks include frequent updates to the World Magnetic Model and increased research on Earth's core dynamics.

"Unraveling the Mystery Behind Earth's Core's 8.5-Year Wobble Cycle"

Scientists from Wuhan University have proposed a new explanation for the mysterious 8.5-year wobble of Earth's inner core, suggesting it is misaligned by 0.17 degrees from the mantle's rotational axis. This finding, published in Nature Communications, challenges the conventional understanding of the core-mantle relationship and could provide insights into the Earth's geomagnetic phenomena. The research, which analyzed polar motion and length-of-day changes, may also help explain variations in the Earth's magnetic field over time.
