摘要：

The problem of grain screening is solved numerically for the case of weakly ionized plasma in the presence of constant external magnetic field. The plasma dynamics is described within the drift-diffusion approach. The spatial distribution of the screened grain potential is studied and compared with the analytical estimates. It is shown that such potential has the Coulomb-like asymptotics with the effective charge dependent on the angle between the radius vector and magnetic field direction. Also, the potential can have nonmonotonic behavior in the direction parallel to magnetic field.
