Electrodynamics of cosmical plasmas-some basic aspects ofcosmological importance

A review is presented of basic electrodynamic properties as revealed by laboratory and space plasma experiments, and their consequences. They include the coupling between magnetic fields and the motion of matter, filamentary and cellular structure, anomalous momentum coupling, and new mechanisms of chemical separation. It is concluded that some of these properties, obviously important for the understanding of the present-day universe, must also have been important in the cosmological evolution of which today's Universe is the result. As some of the crucial properties are still poorly understood, but are being investigated by laboratory and space-plasma experiments, the results of such experiments should also be relevant to the development of cosmology
