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.
André-Marie Ampère. Ampere brought a multitude of phenomena into theory by his investigations of the mechanical forces between conductors supporting currents and magnets. James Clerk Maxwell, in his "A Treatise on Electricity and Magnetism", named Ampere “the Newton of electricity”. [citation needed]
The ampere is named for French physicist and mathematician André-Marie Ampère (1775–1836), who studied electromagnetism and laid the foundation of electrodynamics.In recognition of Ampère's contributions to the creation of modern electrical science, an international convention, signed at the 1881 International Exposition of Electricity, established the ampere as a standard unit of ...
In classical electromagnetism, Ampère's circuital law (not to be confused with Ampère's force law) [1] relates the circulation of a magnetic field around a closed loop to the electric current passing through the loop. James Clerk Maxwell derived it using hydrodynamics in his 1861 published paper "On Physical Lines of Force". [2]
1820 – André-Marie Ampère, professor of mathematics at the École Polytechnique, demonstrates that parallel current-carrying wires experience magnetic force in a meeting of the French Academy of Science, exactly one week after Ørsted's announcement of his discovery that a magnetic needle is acted on by a voltaic current. [17]
André-Marie Ampère (January 22, 1775 – June 10, 1836), was a French physicist who is generally credited as one of the main discoverers of electromagnetism. The SI unit of measurement of electric current, the ampere, is named after him, as well as Ampère's law. Ampère's fame mainly rests on the service that he rendered to science in ...
In 1822, André-Marie Ampère proposed that internal currents are responsible for Earth's magnetism. [2] In 1919, Joseph Larmor proposed that a dynamo might be generating the field. [3] [4] However, even after he advanced his hypothesis, some prominent scientists advanced alternative explanations.
André-Marie Ampère quickly repeated Ørsted's experiment, and formulated them mathematically (which became Ampère's law) . Ørsted also discovered that not only is a magnetic needle deflected by the electric current, but that the live electric wire is also deflected in a magnetic field, thus laying the foundation for the construction of an ...
