It is named after André-Marie Ampère ( 1775 – 1836 ), French mathematician and physicist, considered the father of electrodynamics.

André-Marie Ampère ( 20 January 1775 – 10 June 1836 ) was a French physicist and mathematician who is generally regarded as one of the main founders of the science of classical electromagnetism, which he referred to as " electrodynamics ".

André-Marie Ampère took his first regular job in 1799 as a mathematics teacher, which gave him the financial security to marry Carron and father his first child, Jean-Jacques, the next year.

The death of André-Marie Ampère occurred decades before his new science was canonized as the foundation stone for the modern science of electromagnetism.

The symbol was used by André-Marie Ampère, after whom the unit of electric current is named, in formulating the eponymous Ampère's force law which he discovered in 1820.

They influenced French physicist André-Marie Ampère's developments of a single mathematical form to represent the magnetic forces between current-carrying conductors.

André-Marie Ampère in 1819-1820 ; Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827.

André-Marie Ampère quickly repeated Oestred's experiment, and formulated them mathematically.

Charles-Augustin de Coulomb and André-Marie Ampère's works on electricity and electromagnetism were also recognised, and their units are integrated into the Metric System.

Born in Lyon, he was the only son of the physicist André-Marie Ampère.

Soon after the discovery in 1820 by H. C. Ørsted that a magnetic needle is acted on by a voltaic current, André-Marie Ampère that same year was able to devise through experimentation the formula for the angular dependence of the force between two current elements .< ref >

Several other experiments followed, with André-Marie Ampère, who in 1820 discovered that the magnetic field circulating in a closed-path was related to the current flowing through the perimeter of the path ; Carl Friedrich Gauss ; Jean-Baptiste Biot and Félix Savart, both of which in 1820 came up with the Biot-Savart Law giving an equation for the magnetic field from a current-carrying wire ; Michael Faraday, who in 1831 found that a time-varying magnetic flux through a loop of wire induced a voltage, and others finding further links between magnetism and electricity.

Then in 1820, André-Marie Ampère showed that parallel wires having currents in the same direction attract one another.

André-Marie Ampère also contributed to its development.

André-Marie Ampère achieved the same results three years later by another method ( in his -- On the Determination of Proportions in which Bodies Combine According to the Number and the Respective Disposition of the Molecules by Which Their Integral Particles Are Made ), but the same indifference was shown to his theory as well.

* 1821 — André-Marie Ampère announces his theory of electrodynamics, predicting the force that one current exerts upon another.

In classical electromagnetism, Ampère's circuital law, discovered by André-Marie Ampère in 1826, relates the integrated magnetic field around a closed loop to the electric current passing through the loop.

The first commutator-type direct current machine was built by Hippolyte Pixii in 1832, based on a suggestion by André-Marie Ampère.

In France, the most common case is to give a compound first name, such as Jean-Marie or, more rarely, André-Marie or Bernard-Marie ; more rarely, Marie is used as third or subsequent given name.

In the same year he became Deputy Prime Minister in de facto head of state André-Marie Mbida's government.
