Geomagnetic Shield Weakening Over North America, Claim Chinese Researchers
Chinese scientists have claimed that the magnetic shield over North America is weakening rapidly while strengthening in the eastern hemisphere. Led by Professor Fang Hanxian of the National University of Defence Technology, the study, published in Review of Geophysics and Planetary Physics, claims the shift of the geomagnetic poles from the western to the eastern hemisphere might be the possible reason for the “exceptionally fast” loss of the field strength. Fang’s team used the latest models and data to reconstruct the global magnetic field strength change since 1900. The findings showed that between 1930 to 1990, the field strength in North America increased and was higher than in many other regions of the world. However, over… Read More »Geomagnetic Shield Weakening Over North America, Claim Chinese Researchers
