THEORETICAL STUDY OF THE DISTRIBUTION OF GEOMAGNETIC FLUCTUATIONS.

Abstract

The structure of the magnetohydrodynamic wave equation, with and without a source, is examined both analytically and numerically. Conditions under which the highly anisotropic modes may be neglected are discussed. The lowest eigenfrequencies are found analytically and checked against numerical results. The lowest eigenfrequencies for the toroidal mode (with transverse coupling provided by the time derivative current term in Ohm's law), as discussed by Radoski and McClay, are found. (Author)
