Zong, Qiugang; Fu, Suiyan; Pu, Zuyin; Li, Yaoting Nonlinear effects of the magnetotail particle motion in time-dependent electric field. (English) Zbl 0948.78006 Commun. Nonlinear Sci. Numer. Simul. 1, No. 1, electronic paper No. 8 (1996). Summary: The motion of charged particle in magnetotail-like reversal field with time dependent electric field is studied analytically and numerically using a test particle approach. Variations in the solar wind magnetic and/or velocity can induce a time-dependent electric field in the magnetotail. Interaction of the magnetotail particles with this electric field can give rise to stochasticity. Energy coupling from the field to the plasma is due to stochastic motion of the particles and is termed “stochastic heating” or “stochastic acceleration”. The stochasticity can lead to heating of the plasma and to strong particle acceleration. The process can provide an explanation to the difference between ion and electron temperatures in the plasma sheet.
