Dibner 62; Sparrow 8; Norman 43; DSB I, p.143; Wheeler Gift 762. - Like Oersted, Ampere was a devoted follower of Kant who constructed his own Kantian philosophical system. Ampere's philosophy postulated "two levels of knowledge of the external world ... phenomena, presented to us directly through the senses, and noumena, the objective causes of phenomena" (DSB); this determined the form of his scientific discoveries, of which the most important were his discoveries in electrodynamics, beginning in the fall of 1820. Fascinated by Oersted's demonstration of the existence of electromagnetism, which had been reported by Francois Arago to an astonished Academie des Sciences on September 4, 1820, Ampere immediately set out to determine through his own experiments the exact relationship of electrical current-flow and magnetism. He read his first report to the Academie des Sciences on September 18, 1820. In the present paper, his "first great memoir on electrodynamics" (DSB), probably written soon after November 6, the latest session of the Academic that is mentioned, Ampere describes the series of "classical and simple" experiments with which he first explored the interaction of two electric currents and of electric currents with magnets as well as with the earth's magnetic field. "He demonstrated for the first time that two parallel conductors, carrying currents traveling in the same direction, attract each other; conversely, if the currents are traveling in opposite directions, they repel each other" (Sparrow, Milestones of Science, p. 33). His experiments provided empirical evidence for his new theory of magnetism as "electricity in motion." (DSB).
