Andre-Marie Ampere | Biography, Books, Inventions, & Facts
WEBAndré-Marie Ampère (born January 20, 1775, Lyon, France—died June 10, 1836, Marseille) was a French physicist who founded and named the science of electrodynamics, now known as electromagnetism. His name endures in everyday life in the ampere, the unit for measuring electric current.
André-Marie Ampère - Wikipedia
WEBIn September 1820, Ampère's friend and eventual eulogist François Arago showed the members of the French Academy of Sciences the surprising discovery by Danish physicist Hans Christian Ørsted that a magnetic needle is deflected by an adjacent electric current.
Ampère's force law - Wikipedia
WEBIn magnetostatics, the force of attraction or repulsion between two current -carrying wires (see first figure below) is often called Ampère's force law. The physical origin of this force is that each wire generates a magnetic field, following the Biot–Savart law, and the other wire experiences a magnetic force as a consequence, following the ...
Ampère's Experiments - University of Texas at Austin
WEBAmpère discovered that the force exerted on the test wire is directly proportional to its length. He also made the following observations. If the current in the test wire (i.e., the test current) flows parallel to the current in the central wire then the …
The Pioneer Behind Electromagnetism - IEEE Spectrum
WEBJul 11, 2023 · Through a series of experiments, Ampère discovered that a magnetic field is generated when charge flows through two parallel wires, pushing them apart or pulling them together.

WEBDuring September and October 1820, Ampère, influenced by Ørsted's discovery, performed a series of experiments designed to elucidate the exact nature of the relationship between electric current-flow and magnetism, as well as the relationships governing the behavior of electric currents in various types of conductors.
André Marie Ampère and his contribution to electromagnetism
WEBAndré Marie Ampère, (born Jan. 22, 1775, Lyon, France—died June 10, 1836, Marseille), French physicist, founder of the science of electromagnetism. A prodigy who mastered the entire known field of mathematics by age 12, he became a professor of physics, chemistry, and mathematics.
WEBThe purpose of this experiment is to verify Ampere’s law. You will measure the magnetic field due to a current-carrying coil of wire on a path enclosing a portion of the coil. Equipment: GMR sensor and 12.0V transformer, multimeter, 1500 turn circular coil, power supply, two cables, ruler.
