Eletrodinâmica de ampère: uma interpretação e dedução da força de ampère a partir dos quatro casos de equilíbrio descritos no thèori

Abstract

The French physicist Andrè Marie Ampere had a fundamental scientific contribution in the study of electrical currents and of magnetism , unifying the model of this phenomena in a single formula of force. Then he created the noun " electrodynamic ", and the new field of physics defined by this concept. The apex of his work was the conception of a new experimental method which he used to find the mathematical expression for the force between current elements. In our work , we will explain the four cases of equilibrium which are described in Ampere's main work ( the Theory of Electrodynamic Phenomena Uniquely Deduced from Experience) we will explore some details not developed in the literature, finaly we will arrive at the complete expression describing the interaction of steady currents.
