Introduction
André-Marie Ampère made the revolutionary discovery that a wire carrying electric current can
attract or repel another wire next to it that’s also carrying electric current. The attraction is
magnetic, but no magnets are necessary for the effect to be seen. He went on to formulate Ampere’s
Law of electromagnetism and produced the best definition of electric current of his time.
Ampère also proposed the existence of a particle we now recognize as the electron, discovered the
chemical element fluorine, and grouped elements by their properties over half a century before
Dmitri Mendeleev produced his periodic table.
The SI unit of electric current, the ampere, is named in his honor.

Contribution
#1 HE RECOGNIZED THE EXISTENCE OF THE ELEMENT FLUORINE AND COINED ITS
TERM IN 1810, Andre-Marie Ampere proposed that hydrofluoric acid was a compound of hydrogen
and an unknown element, which he said had properties similar to chlorine. He coined the word
fluorine for this element and suggested that it could be separated by electrolysis. After 76 years,
French chemist Henri Moissan finally isolated fluorine. He does this by electrolysis, as Ampere
suggested.
#2 HE CORRECTLY IDENTIFIED THAT CHEMICAL ELEMENTS SHOULD BE ORGANIZED
ACCORDING TO THEIR PROPERTIES
In 1816, Ampere proposed that chemical elements should be listed according to their properties. Only
48 elements were known at that time and Ampere tried to fit them in 15 groups. Though his attempt
to form a reasonably accurate periodic table fell far short, he did successfully group the alkali metals,
the alkali earth metals and the halogens. It was 53 years after Ampere’s attempt that Russian chemist
Dmitri Mendeleev published his renowned periodic table.
#3 IN ELECTROMAGNETISM, HE CREATED THE RIGHT-HAND GRIP RULE, WHICH IS
VERY WELL-KNOWN.
Hans Christian Oersted, a Danish scientist, observed in April 1820 that an electric current flowing
through a wire deflected a nearby magnetic needle. Andre-Marie Ampere became engaged in this
new field of inquiry after discovering it. He devised the Ampere's right-hand grip rule to determine
the direction of a compass needle's deflection in relation to the direction of electric current flow along
a wire. If the observer's right hand is imagined clutching the wire through which the current runs,
with the thumb pointing in the direction of the current, then this rule applies. The fingers then curl
around the wire, indicating

Inventions
He invented the astatic needle, a critical component of the modern astatic galvanometer, and was
the first to demonstrate that a magnetic field is generated when two parallel wires are charged with
electricity. He is generally credited as one of the first to discover electromagnetism. He discovered
that an electric current through a coil act like a magnet. This discovery led to the invention of the
alvanometer, an instrument for detecting and measuring electric currents. With the alvanometer he
proved that electric current makes a circuit through a battery.
The ampere, a unit used to measure the rate of flow of an electric current, is named after him.
During 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 currentflow and magnetism, as well as the relationships governing the behavior of electric currents in
various types of conductors. Among others, Ampère showed that two parallel wires carrying
electric currents magnetically attract each other if the currents are in the same direction and repel if
the currents are in opposite directions.
Ampere´s Law
Ampère
had discovered something amazing: he had produced magnetic attraction and repulsion in the
complete absence of any magnets. All the magnetism was generated electrically. He called this new
field electrodynamics. (Today electrodynamics and electromagnetism are regarded as the same field.)

Biography André-Marie Ampére
André-Marie Ampère, (born January 20, 1775, Lyon, France—died June 10, 1836, Marseille), 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.
Ampère, who was born into a prosperous bourgeois family during the height of the
French Enlightenment, personified the scientific culture of his day. His father, Jean-Jacques Ampère,

was a successful merchant, and also an admirer of the philosophy of Jean-Jacques Rousseau, whose
theories of education, as outlined in his treatise Émile, were the basis of Ampère’s education.
Rousseau argued that young boys should avoid formal schooling and pursue instead an “education
direct from nature.” Ampère’s father actualized this ideal by allowing his son to educate himself
within the walls of his well-stocked library. French Enlightenment masterpieces such as GeorgesLouis Leclerc, comte de Buffon’s Histoire naturelle, générale et particulière (begun in 1749)
and Denis Diderot and Jean Le Rond d’Alembert’s Encyclopédie (volumes added between 1751 and
1772) thus became Ampère’s schoolmasters. In addition, he used his access to the latest mathematical
books to begin teaching himself advanced mathematics at age 12. His mother was a devout woman,
so Ampère was also initiated into the Catholic faith along with Enlightenment science. The French
Revolution (1787–99) that erupted during his youth was also formative. Ampère’s father was called
into public service by the new revolutionary government, becoming a justice of the peace in a small
town near Lyon. Yet when the Jacobin faction seized control of the Revolutionary government in
1792, Jean-Jacques Ampère resisted the new political tides, and he was guillotined on November 24,
1793, as part of the Jacobin purges of the period.
In 1802 Ampère was appointed a professor of physics and chemistry at the École Centrale in Bourgen-Bresse. He used his time in Bourg to research mathematics, producing Considerations sur la
théorie mathématique de jeu (1802; “Considerations on the Mathematical Theory of Games”), a
treatise on mathematical probability that he sent to the Paris Academy of Sciences in 1803. After the
death of his wife in July 1803, Ampère moved to Paris, where he assumed a tutoring post at the
new École Polytechnique in 1804. Despite his lack of formal qualifications, Ampère was appointed
a professor of mathematics at the school in 1809. In addition to holding positions at this school until
1828, in 1819 and 1820 Ampère offered courses in philosophy and astronomy, respectively, at
the University of Paris, and in 1824 he was elected to the prestigious chair in experimental physics at
the Collège de France. In 1814 Ampère was invited to join the class of mathematicians in the new
Institut Impériale, the umbrella under which the reformed state Academy of Sciences would sit.
