A related animation by the same authors that shows charge separation and creation of an electric field. In this model, five negative and five positive charges of equal magnitude are shown. The positive charges are separated one-by-one at constant velocity. It clearly depicts how the electric field grows as each positive charge is moved into place.

A 3D interactive simulation of the electric field of two equal and opposite charges, depicted in a "grass seeds" representation. The observation point may be moved in positive or negative directions along x, y, or z.
