André-Marie Ampère (UK: / ˈ æ m p ɛər /, US: / ˈ æ m p ɪər /; [1] French: [ɑ̃dʁe maʁi ɑ̃pɛʁ]; 20 January 1775 – 10 June 1836) [2] was a French physicist and mathematician who was one of the founders of the science of classical electromagnetism, which he referred to as electrodynamics.
Danish physicist Hans Christian Ørsted accidentally discovered that an electric field creates a magnetic field. 1820: One week after Ørsted's discovery, French physicist André-Marie Ampère published his law. He also proposed the right-hand screw rule. 1821: German scientist Thomas Johann Seebeck discovered thermoelectricity. 1825
The discovery of electromagnetic induction was made almost simultaneously, although independently, by Michael Faraday, who was first to make the discovery in 1831, and Joseph Henry in 1832. [ 77 ] [ 78 ] Henry's discovery of self-induction and his work on spiral conductors using a copper coil were made public in 1835, just before those of Faraday.
The Ampère Museum is a museum of the history of electricity dedicated to André-Marie Ampère (1775–1836). The museum is located in Poleymieux-au-Mont-d'Or at approximately 15 km (9.3 mi) from Lyon by road and is housed in the house where André-Marie Ampère spent part of his youth.
Portal:Electronics/Selected biography/3 . Nikola Tesla (10 July 1856 - 7 January 1943) was an inventor, electrical and mechanical engineer known for his patents and theoretical work that contributed to modern alternating current electric power (AC) systems, including the polyphase power distribution systems and the AC induction motor.
Life made the modern Earth as much as the Earth made life, a new book by a philosopher of consciousness argues. That dynamic leaves humans with a unique set of moral questions, Peter Godfrey-Smith ...
Walter M. Elsasser, considered a "father" of the presently accepted dynamo theory as an explanation of the Earth's magnetism, proposed that this magnetic field resulted from electric currents induced in the fluid outer core of the Earth. He revealed the history of the Earth's magnetic field through pioneering the study of the magnetic ...
This made a practical electric telegraph possible. He was the first to coil insulated wire tightly around an iron core in order to make an extremely powerful electromagnet, improving on William Sturgeon's design, which used loosely coiled, uninsulated wire. He also discovered the property of self inductance independently of Michael Faraday.
