64. Electro-Magnetic Induction
Ever since Ørsted's discovery in 1820, scientists were trying to find the opposite effect, where magnetism would generate electricity. Finally, in 1831, Faraday achieved success by generating an electric current from electromagnetic induction. This discovery was the first of many of his electrical papers reprinted in a classic three-volume set.
