FIELD REVERSALS OF "PALEOMAGNETIC" TYPE IN COUPLED DISK DYNAMOS

Abstract

Rikitake's adaptation of Bullard's simplified disk-dynamo model for the dynamo theory of the geomagnetic dipole was investigated further by means of an analog computer. A modified model having generalized interaction, which was suggested by an axial configuration, was also studied. A striking similarity is observed be tween the computer solutions and the geomagnetic polarity reversals inferred from paleomagnetic studies. Thus the magnetofluiddynamic origin of the earth's field becomes more plausible.
