This is an animation of the destruction of an electric field. It begins with five negative and five positive charges, all of equal magnitude and separated by a distance L in space. One by one, the five positive charges are moved at constant velocity from their initial position to the location of the negative charges. The user can observe the strength of the electric field decreasing as each positive charge is moved into place.
EDITOR'S NOTE: We suggest using this animation with a closely related model by the same authors showing the opposite phenomenon: creation of an electric field by charge separation. SEE RELATED MATERIALS for a link to MIT 8.02: Creating an Electric Field.

A companion animation by the same authors that depicts the opposite phenomenon: the creation of an electric field through charge separation. Strength of field increases as positive charges are moved one-by-one to a location of L distance from the initial position.
