Presented is a discussion of the events of the 20-year lapse between the invention of the pile in 1800 by Volta, and Hans Christian Oersted's famous definitive paper "Effects of a Current of Electricity on the Magnetic Needle." Students are thus enabled to appreciate the climate of the time and the manner and significance of Oersted's…

PDF pending restorationDevons, Samuel – 1975
This paper focuses on the search for electromagnetic induction from 1820 to 1831 and the efforts by Augustin Fresnel's colleague, Andre Marie Ampere, in electric and magnetic induction. Faraday's work is discussed with excerpts from his diary on electromagnetism. A variety of different experiments by researchers including Francoise Jean Arago,…

Devons, Samuel – 1975
This paper describes the events following the news of Oersted's discovery of the effects of a current of electricity on a magnetic needle. It focuses on Biot and Savart's law which expresses the force between a current element and a "molecule of magnetism" that can be deduced from Ampere's law of interaction between two current elements.…

Ahrens, Walter R.; Harley, Theodore L.; Burns, Elmer E. – P. Blakiston's Son & Co., 1917
While the new movement in the teaching of physics--the study of the physics of daily life--is the keynote of the recent text-books, yet the laboratory manuals still adhere to the old method, leaving the presentation of material from everyday life to the text-book alone. It is the authors' belief that the manual as well as the text-book should be…
