Computer simulations were carried out on the spatial distribution of small Al 2 O 3 particles dumped into the Earth's magnetosphere during solid rocket propellant burns. In addition to the standard gravitational and light pressure forces, we have taken into account the electrodynamic forces as the particle will be electrostatically charged because it is immersed in the plasma and radiative environment of the Earth. We will conclude that the lifetime of a grain in the magnetosphere is not sensitive to the electrodynamic forces but the number of grains lost to the solar wind will dramatically increase at the expense of the flux lost by colliding with the Earth.
