This biography of Michael Faraday helps you learn English through real historical stories. Explore Michael Faraday's impact on the world.
Michael Faraday was born in 1791 in London to a poor, working-class family. Receiving only a basic formal education, he began working as an errand boy and later an apprentice bookbinder at the age of 14. Surrounded by books, he developed a voracious appetite for reading, particularly works on science and electricity. His life changed completely in 1812 when he attended lectures by the eminent chemist Humphry Davy. Faraday bound his detailed notes from these lectures into a book and sent them to Davy, who was so impressed that he hired the young man as his laboratory assistant.
Working at the Royal Institution, Faraday transitioned from a humble assistant into one of the greatest experimental scientists in history. In 1821, he built the first electric motor, demonstrating that electrical energy could be converted into mechanical motion. A decade later, in 1831, he made his most crucial breakthrough: electromagnetic induction. By moving a magnet through a coil of copper wire, he generated an electric current. This monumental discovery proved that magnetism could produce electricity, leading directly to the invention of the electric transformer and the electric generator, the very foundation of the modern power grid.
Despite his lack of advanced mathematical training, Faraday's brilliant physical intuition allowed him to visualize invisible forces, introducing the concept of "lines of force" or electromagnetic fields. He also made major contributions to chemistry, including the discovery of benzene and the laws of electrolysis. In 1836, he invented the "Faraday cage," an enclosure that blocks external electromagnetic fields. A deeply humble and religious man, Faraday repeatedly declined a knighthood and the presidency of the Royal Society. Today, he is universally celebrated as the scientist who took electricity from a scientific curiosity and transformed it into a viable, world-changing source of power.
