Recent investigations into the geodynamo have focused on refining simulation models to better capture the intricate dynamics of core convection and magnetic field generation.

In the kinematic dynamo problem Maxwell's equations are solved for the magnetic field given a prescribed fluid velocity. Although no dynamic equations are involved, it does provide an accurate link ...

Abstract: In recent numerical simulations of the geodynamo the dynamo action is driven, primarily, by the effects of helicity, with differential rotation playing only a secondary role. These dynamos ...

Earth’s magnetic field has correlated with fluctuations in atmospheric oxygen, according to a newly released study.
