Inner-core conductivity in numerical dynamo simulations
J Wicht - Physics of the Earth and Planetary Interiors, 2002 - Elsevier
Speculation about its possible super-rotation has drawn the attention of many geophysical

Correlation of Earth's magnetic field with lower mantle thermal and seismic structure
Variations in the Earth's lower mantle appear to influence the geodynamo operating in the
liquid core. We present a solution to the full dynamo equations with lateral variations in heat …

On a dynamo driven by topographic precession
CC Wu, PH Roberts - Geophysical and Astrophysical Fluid …, 2009 - Taylor & Francis
More than half a century ago, Bullard suggested that the Earth's dynamo might be driven by
the motions created in the Earth's core by the luni-solar precession. The precessionally …
