The author comments on Dr. Carpenter´s paper 6613A (S8) (see IEE Proc. A, 1989, vol.136, no.3, p.101-13) in which he states that Maxwell´s equations ´when integrated in space, require that E at some point P depends on changes in B at points remote from P, but coincident in time, and likewise that H depends on simultaneous, but remote, values of J and D´. He demonstrates Maxwell´s so-called ´displacement current´ and suggest that perhaps the time has come to teach electromagnetism this way. The author of the original article states that he agrees entirely with almost everything Dr. Allen says and expands on some of his statements.
