A numerical analysis of the high-speed plasma flow and the electromagnetic field around a magnetic dipole was performed to investigate acceleration processes of the Magnetoplasma Sail (MPS). In an attempt to take into account deviations of the flow characteristics from the ideal magnetohydrodynamic (MHD) predictions, the particle-in-cell (PIC) model was used with a reduced dimension of the flow and the electromagnetic field. The induction current and the induced electromagnetic field around the magnetic dipole were computed, and the acceleration force acting on the magnetic dipole was roughly estimated. Important scaling parameters in an interaction between the rarefied high-speed plasma and the weak magnetic field are also discussed.
