The graphics in this simulation do an excellent job displaying the field structure. The ability to adjust the viewing angle is of great value in this respect. There are a large number of views available, including 3-dimensional as well as X, Y, or Z slices. The distribution type, number of particles, field strength, and charge separation can all be varied. Available displays include field lines, field vectors, and equipotential surfaces. Each simulation can stopped, reversed, or reset as well.
