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.

The original "Absolute Ampere" was defined as 0.1 Electromagnetic units. The original "International Ampere" was defined electrochemically as the current required to deposit 1.118 milligrams of silver per second from a solution of silver nitrate. Compared to the SI ampere, the difference is 0.015%. I kelvin: K thermodynamic temperature

In physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields.The electromagnetic force is one of the four fundamental forces of nature.
The interaction is mediated by the magnetic field each current produces and forms the basis for the international definition of the ampere. [53] The electric motor exploits an important effect of electromagnetism: a current through a magnetic field experiences a force at right angles to both the field and current.
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.
