  We consider a stochastic differential equation for a charged particle in a
stochastic magnetic field, known as A-Langevin equation. The solution of the
equation is found, and the Lagrange velocity correlation function is calculated
in Corrsin approximation. A corresponding diffusion constant is estimated. We
observe different transport regimes, such as quasilinear- or Bohm-type
diffusion, depending on the parameters of plasma.
