A year earlier he had been earning the staggering sum of #1,000 a year as a scientific consultant. Now Michel Faraday was devoting himself exclusively to sum. But the cut in pay was worth it. He had long been convinced that magnetism and electricity were closely related. Already he knew that an electric current could produce magnetism, and on August 24, 1831, during an epoch-making period of nine days of brilliant experimentation of the Royal Society in London, he proved that magnetism could produce electricity. Using very simple equipment ( a magnet, a copper coil, and a basic ammeter), he demonstrated that moving a wire through a magnetic field induces an electric current whose voltage is proportional to the speed of the movement. Here was, in effect of the world's first dynamo. The principle that he has discovered underlies the fundamental operation of most modern-day electrical machines. Faraday was not only a brilliant experimental scientist but also one of the most practical.
Born in 1791, the son of a poor Yorkshire blacksmith, amazingly, Faraday had little formal education. He was an apprentice to bookbinder before attracting the attention of Sir Humphrey Davy and becoming a dedicated chemist and physicist, and a superb lecturer. He discovered Benzene, invented the system of oxidation numbers, devised an early form of the Bunsen burner, developed the laws of electrolysis, and helped along the birth of nanoscience, as well as giving us the "Faraday cage," the "Faraday constant," and the "Faraday effect."
More than any other man, Michael Faraday made possible the generation of electricity. It took another generation before his discoveries found full practical expression, but humankind is in his debt.
