Generation of quasi-stationary magnetic fields by external electromagnetic radiation in a cold magneto-active plasma
Abstract
Starting from the hydrodynamic equations for a cold electron fluid, we develop a theory of the ponderomotive effect of the interaction of high-frequency electromagnetic radiation with a magneto-active plasma. Using the method of averaging on high-frequency oscillations, we obtain expressions for the low- frequency nonlinear currents. We also obtain an equation describing the space-time evolution of a quasi-stationary magnetic field in the plasma.
