MAGNETOHYDRODYNAMICS OF THE EARTH'S MAGNETIC FIELD.
Abstract
A survey of observational and theoretical work pertaining to the origin of planetary magnetic fields is given with special emphasis on the dynamo theory which attempts to explain these fields as arising from magnetohydrodynamic regenerative action. Some points are raised regarding what a satisfactory theory should contain. It is suggested that reversals may occur without a drastic change in the internal flow. A method of using one model of dynamo action to obtain information about the structure of the flow in the core of the earth is proposed.
