Ampère, André-Marie

SUBJECT AREA: Electricity
b. 22 Jan 1775 Lyon, France
d. 10 June 1836 Marseille, France
French physicist and mathematician who established laws and principles relating magnetism and electricity to each other.
Ampère was reputed to have mastered all the then-known mathematics by the age of 12. He became Professor of Physics and Chemistry at Bourg in 1801 and a professor of mathematics at the Ecole Polytechnique in Paris in 1809. Observing a demonstration in 1820 of Oersted's discovery that a magnetic needle was deflected when placed near a current-carrying wire, Ampère was inspired to investigate the subject of electricity, of which he had no previous experience. Within a week he had prepared the first of several important communications on his discoveries to the Academy of Sciences in Paris. Included was a new hypothesis formed on the basis of his experiments on the relation between electricity and magnetism. He investigated the forces exerted on each other by current-carrying conductors and the properties of a solenoid. His mathematical theory describing these phenomena provided the foundations for the development of electro-dynamics and his classic work Théorie mathématique des phénomènes électro-dynamiques was published in 1827.
The name "ampere" was adopted to replace the name "weber" as a unit of current after Helmholtz proposed such a change in 1881.
