  author={Gary A. Glatzmaiers and P. Roberts},
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 conducting inner core, undergoes several polarity excursions and then, near the end of the simulation, a successful reversal of the dipole moment. This simulated magnetic field reversal shares some features with real reversals of the geomagnetic field, and may provide insight into the geomagnetic reversal mechanism. 
Simulations of a Quasi–Taylor State Geomagnetic Field Including Polarity Reversals on the Earth Simulator
High-resolution, low-viscosity geodynamo simulations have been carried out on the Earth Simulator in a dynamic regime similar to that of Earth's core, that is, in a quasi–Taylor state, and exhibit features of the geodynamics not only in spatial and temporal characteristics but also in dynamics.

Reversals of the Geomagnetic Field: Constraint on Convection Intensity in the Earth’s Core
Abstract Modern geodynamo models allow the generation of a magnetic field without reversals and with frequent reversals. The transition from one regime to another is associated with a relativelyExpand
Modeling the Earth's dynamo
For the past decade, three-dimensional time-dependent computer models have been used to predict and explain how the geomagnetic field is maintained by convection in the Earth's fluid core. GeodynamoExpand

Geomagnetic field morphologies from a kinematic dynamo model
THE Earth's magnetic field is generated by flow of liquid iron in the outer core, acting as a dynamo. In the simple kinematic theory a fluid flow is prescribed and tested for its ability to generateExpand

Influence of the Earth's inner core on geomagnetic fluctuations and reversals
IN view of its relatively small size (one-third the radius of the outer core), many geodynamo models neglect the inner core entirely1, or otherwise treat it as a non-conducting insulator2,3. In aExpand
