Abstract

In this paper the effects of diffusion in a stochastic magnetic field are discussed. The time-dependent equations for diffusion flux and ambipolar electric field are derived. The results show that the relaxation time is much less than the life-time of particles, so that the quasi-stationary state can be reached. The ambipolar electric field is important and the ambipolar diffusion flux is of the same order of the ion diffusion level.
