A eletrodinâmica de Weber e seus desenvolvimentos recentes

Abstract

We show how Maxwell's equations can be derived from Weber's electrodynamics Ampere's force between current elements can also be derived from it. We discuss experiments related to Ampere's force and to the existence or not of an electric field outside a dc current carrying wire. Finally we avalyse recent theoretical developments in Weber's electrodynamics introduction of the retarded time and the existence of terms of third and higher orders of v2/c2 in a generalized Weber's force.
