This paper presents results on the visualisation of tracks of charged particles in a non-uniform magnetic field. The field modelled is that generated by a coil driven by DC current.

The motion of typical particles, such as electrons, ions and multiply-charged heavy particles has been simulated.  The motion is initially assumed to be in vacuum, so that collisions with neutral particles can be ignored. This could simulate, for example, the motion of auroral particles in the higher atmosphere. Results are also presented for ambient atmospheric pressure conditions by introducing the weakly compressible Navier-Stokes flow equations. This simulates particle flows in man-made devices such as ion generators.
