Both. New field is created, and the old tries to catch up. The field tries to "catch up" at the speed of light. In a sense this is what is happening with an antenna. The magnet gets "made and destroyed" rather than being moved, and the result is EM waves. So you could say that a photon comprises the retarded field. IOW if you could move the magnet fast enough it would radiate. (In an antenna the little magnets called electrons get moved very fast). Note the time of day of this post, and be gentle in your response. ;) Regards, Robin van Spaandonk http://users.bigpond.net.au/rvanspaa/ Competition provides the motivation, Cooperation provides the means.
