What is ampere contribution?
Among other things, Ampere was the first to discover that magnetism could be produced without magnets; wrote the foundational test of electromagnetism; and formulated the Ampere’s force law. He also played a key role in the development of the galvanometer; and invented and coined a term for solenoid.
What is the contribution of André-Marie Ampere?
He invented the astatic needle, a critical component of the modern astatis 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.

What was Andre Marie Ampere famous for?
André-Marie Ampère. 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.
In 1845, just 170 years ago, Faraday discovered that a magnetic field influenced polarized light – a phenomenon known as the magneto-optical effect or Faraday effect. He discovered electromagnetic induction, which led to the invention of the dynamo, the forerunner to the electric generator.
What was the name of Andre Marie Ampere’s daughter?
A second daughter Josephine was born when André-Marie was eight. The education André-Marie received was rather unusual. His father was a great admirer of Jean-Jacques Rousseau, one of the leaders of the French Enlightenment. He decided to follow Rousseau’s approach for André-Marie’s education.
Where did Andre Marie Ampere live most of his life?
Early life. André-Marie Ampère was born on 20 January 1775 to Jean-Jacques Ampère, a prosperous businessman, and Jeanne Antoinette Desutières-Sarcey Ampère, during the height of the French Enlightenment. He spent his childhood and adolescence at the family property at Poleymieux-au-Mont-d’Or near Lyon.
When did Julie Carron and Andre Marie Ampere get married?
In 1796 Ampère met Julie Carron, and in 1799 they were married. 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 (named after his father), the next year.
How did Andre Marie Ampere contribute to electrodynamics?
Ampère solidly established his electrodynamics by basing it on inverse-square forces (which,… …same year, another French physicist, André-Marie Ampère, developed Ørsted’s observations in quantitative terms. Ampère showed that two parallel wires carrying electric currents attract and repel each other like magnets.
