ANDRE MARIE AMPERE (1775 - 1836)
Andre Marie Ampere was one of the founders of the science of electromagnetics. He propounded the laws of electromagnetism and showed that a magnetic field is associated with a current flowing through a conductor. Unit of electric current is Ampere, comes from his name. If one coloumb unit of electric charge flows in any part of an electrical conductor in one second then it is one ampere.
Ampere was born on 2 January, 1775 in France. His father was a Jute merchant and a well read man. He introduced Latin and Greek to his son. Ampere when he was child he was solving Arithmetic problems using small stone pebbles. At 11 he had a thorough knowledge in mathematics and calculus.
Those were the days of French revolution. His father was sentenced to death. Ampere was mentally shocked. He had lost his paternal property. He had to earn his livelihood by private tuitions. He married Julie. She gave birth to his son. Ampere got an appointment as teacher in a High school. He worked there for two years and then joined an engineering college in Paris.
In 1819 Johanne C. Oersted of Denmark performed an experiment in which he observed a magnetic needle moving near a wire carrying current. Ampere conducted an experiment to find out the effect of electricity on a magnetic needle. His discoveries helped electrodynamics. It was confirmed that magnets can be developed with the help of electricity. When electricity flows through a coil it gets magnetized and the current starts from its origination and returns through a circuit. Ampere published his book on magnetism and electricity in 1823. He said that molecular electricity causes magnetism. Later it was made known that the flow of electrons constitute current.
