Abstract

A three-dimensional numerical simulation of the interaction between a high-velocity aluminum plasma jet and the geomagnetic field has been performed, based on the injection scenario derived from the North Star II experiment. The simulation results demonstrate the excitation of Alfvén waves, expulsion of the magnetic field, dynamics of the diamagnetic cavity, deceleration of the jet, and induced motion in the background plasma. The calculated parameters show agreement with experimentally measured ion densities.
