Motion of a Charged Particle in Given Fields
Astrophysical plasma is often an extremely tenuous gas of charged particles, without net charge on average. If there are very few encounters between particles, we need only to consider the responses of a particle to the force fields in which it moves. The simplest situation, a single particle in given fields, allows us to understand the drift motions of different origin and electric currents in such collisionless plasma.
