In 1995, two groups [Kageyama et al., 1995; Glatzmaier and Roberts, 1995a, 1995b]
reported results of numerical integrations of fully three‐dimensional, fully nonlinear …

A three-dimensional, self-consistent numerical model of the geodynamo is described, that
maintains a magnetic field for over 40,000 years. The model, which incorporates a finitely …

Of the terrestrial planets, Earth and probably Mercury possess substantial intrinsic magnetic
fields generated by core dynamos, while Venus and Mars apparently lack such fields …

Convection in Earth's fluid core is regarded as a small deviation from a well-mixed adiabatic
state of uniform chemical composition. The core is modeled as a binary alloy of iron and …

The solar dynamo continues to pose a challenge to observers and theoreticians.
Observations of the solar surface reveal a magnetic field with a complex, hierarchical …

Cosmic magnetic fields, including the fields of planets, stars, and galaxies, are believed to
be caused by dynamo action in moving electrically conducting fluids. While the theory and …

The generation of a magnetic field in an electrically conducting fluid generally involves the
complicated nonlinear interaction of flow turbulence, rotation and field. This dynamo process …

The Earth's magnetic field is sustained by dynamo action in the fluid outer core. The energy
sources available to the geodynamo are well established, but their relative importance …

Numerical solutions to the magnetic induction equation in a sphere have been obtained for
a number of stationary velocity models. By searching for non-steady magnetic fields and in …

The evolution of the Earth's outer core is calculated theoretically by assuming that the
fluctuations about a vigorously convecting, well-mixed, isentropic and hydrostatic mean state …
