The so-called Lienard-Wiechert potentials constitute a fundamental part of basic electromagnetic theory. Through these potentials both the electric and the magnetic fields are accordingly derived, and in following steps Maxwell’s Equations may also be derived. Short-to-say, if succeeding in showing any fundamental fallacy in the derivation of the Liénard-Wiechert potentials, one could claim to have falsified whole Maxwell’s theory, a very important prerequisite if intending to pave the way for a radically new theory. Yet, the author does not intend to create a new theory of his own. Instead, at hand is an attempt to give credit to the far older theory than Maxwell’s, namely basically Coulomb’ s Law of 1785 (or Cavendish 1771).
The author has earlier published a paper where this is done with respect to experiments performed upon Ampere’s Bridge in the early 1980´s. In this paper the focus is on the way retarded potentials are derived.
The author succeeds in showing that Feynman in his derivation of the Liénard-Wiechert Potentials in the famous “Feynman’s Lectures on Physics” counts the same charge twice, hence attaining a wrong expression for the electric potential, provided one is using the very idea of potentials
