A companion animation by the same authors that depicts the opposite phenomenon: the destruction of an electric field. It begins with five positive and five negative electric charges separated by a distance L in space. One-by-one, the positive charges are moved to the position of the negative charges, with strength of field decreasing as each charge is moved into place.

This related animation by the same authors shows the separation of one positive and one negative charge of equal magnitudes, resulting in the classic electric dipole field pattern.
