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 ...
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.
Ampere balance, an electromechanical apparatus for precise measurement of the ampere Ampère's circuital law , a rule relating the current in a conductor to the magnetic field around it Ampère's force law , the force of attraction or repulsion between two current-carrying wires
The best-known and simplest example of Ampère's force law, which underlaid (before 20 May 2019 [1]) the definition of the ampere, the SI unit of electric current, states that the magnetic force per unit length between two straight parallel conductors is
This leads to the definition of the magnetic dipole moment as: = (), where × is the vector cross product, r is the position vector, and j is the electric current density and the integral is a volume integral.
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.
