Washington, July 4 (ANI): Scientists have performed numerical calculations that show how convective mixing flows in the Earth's liquid outer core can cause the geomagnetic dipole to collapse.
In particular, the researchers found that a mixing flow in the outer core with magnetic Reynolds number in the range of 200, which they suggest is a physically reasonable range, could account for the historically measured rate of decrease of the geomagnetic dipole moment.
