Gyre-driven decay of the Earth’s magnetic dipole
The magnitude of the Earth’s magnetic dipole has decreased by 9% over the past 175 years. Here, the authors suggest that the rate of dipole decay is controlled by a huge gyre in the liquid metal outer core acting on a field asymmetry, and that decay is set to continue for the next few decades.
