I do not quite see the physics problems with this animation mentioned in the description. It is only the the color coding that is a bit confusing: strong fields are shown in red whether they are positive or negative, but weaker fields have different colors for opposite signs. In his comment in the file description, Rainald62 refers to the Mathematica code for this image. Where can I find that? /Pieter Kuiper (talk) 10:36, 6 February 2012 (UTC)
