“Ampère . . . heard of Oersted’s discovery [of electromagnetism] and immediately set up a series of experiments to determine the exact relationships of current-flow and magnetism. In a week Ampere presented the first of a series of papers establishing the laws of forces acting between conductors carrying
current”

Mémoire présenté à l'Académie royale des sciences, le 2
octobre 1820, . . . sur les effets des courans
électriques. WITH: Suite du mémoire sur l'action
mutuelle entre deux courans électriques, entre un
courant électrique et un aimant ou le globe terrestre,
et entre deux aimans. In, Annales de chimie et de physique, vol. 15
(1820): 59-76; 170-218 The whole volume (448pp.) offered. Paris:
Crochard, 1820. Octavo, recent period-style paneled calf. With 5
engraved plates illustrating Ampere's work. $5200. First printings of Ampère's landmark papers laying the groundwork for electromagnetic theory. When Ampère " learned of Danish physicist Hans Christian Ørsted's discovery in 1820 that a magnetic needle is deflected when the current in a nearby wire varies—a phenomenon establishing a relationship between electricity and magnetism—Ampère prepared within a week the first of several papers fully expounding the theory of this new phenomenon. He formulated a law of electromagnetism (commonly called Ampère's law) that describes mathematically the magnetic force between two electric currents. He also performed many experiments, the results of which served to develop a mathematical theory that not only explained electromagnetic phenomena already reported but predicted new ones as well." Ampère founded and named the new field of electrodynamics (later electromagnetism) to accurately describe his theory of magnetism as electricity in motion. Fine condition in beautiful period-style paneled calf. Provenance: The Smithsonian Institute, with their stamp on general title page. plates of Ampère's experiments, please click to enlarge:
