Jan 20, 2018 · In addition to establishing electrodynamics, Ampère recognised the principle of electric telegraphy (proposal of an electromagnetic telegraph with Jacques Babinet in 1822), which was not very practical over long distances. André-Marie Ampère published his most important and most influential work was published in 1826.
Jul 11, 2023 · French physicist André-Marie Ampère investigated the behavior of an electric current in a magnetic field. One of his experiments consisted of a loop of wire suspended in small cups of mercury so that it can pivot freely while each end is in constant electrical contact with a battery.

Scientific understanding into the nature of electricity grew throughout the eighteenth and nineteenth centuries through the work of researchers such as André-Marie Ampère, Charles-Augustin de Coulomb, Michael Faraday, Carl Friedrich Gauss and James Clerk Maxwell .
By placing, with the physicist Arago, a soft iron core in the centre of a helix, which he baptised solenoid, he invented the temporary magnetisation that is the basis for the electromagnet. It rotated a permanent magnet through which a current would flow prefiguring the electric motor.
His contributions laid the groundwork upon which the science of electrodynamics (a term coined by Ampère, but now more commonly referred to as electromagnetics) has been built. Ampère was a native of Lyon, France, born January 22, 1775. As a child, he proved prodigious in mathematics.
Jun 8, 2018 · He founded electrodynamics (now called electromagnetism) and performed numerous experiments to investigate the magnetic effects of electric currents. He devised techniques for detecting and measuring currents, and constructed an early type of galvanometer.
