A conceptual model of core dynamics and the Earth's magnetic field

Main Article Content

C.B. Officer


A conceptual model of core dynamics and the Earth's magnetic field is presented. It differs from previous investigations in the use of an estimated core viscosity of 2 x 107 cm2 s- 1. The simplified derivations predict the correct order of magnitude for the external magnetic field and for the westward drift of the nondipole field.
