We consider non-linear transport and drift processes caused by an inhomogen
eous magnetic field in a turbulent fluid. The coefficients of magnetic diff
usivity and drift velocity are calculated by making use of the second-order
correlation approximation. Transport processes in the presence of a suffic
iently strong magnetic field become anisotropic with larger diffusion rate
and turbulent electrical resistivity across the field than along the field.
Non-linear effects also lead to a drift of the magnetic field away from th
e regions with a higher magnetic energy.
