Faraday's experiments yielded some of the most significant principles and inventions in scientific history. He developed the first dynamo (in the form of a copper disk rotated between the poles of a permanent magnet), the precursor of modern dynamos and generators. From his discovery of electromagnetic induction (1831 also independently discovered by the American Joseph Henry ) stemmed a vast development of electrical machinery for industry. In 1825 he discovered the compound benzene . In addition to other contributions he did research on electrolysis , formulating Faraday's law . He also laid the foundations of the classical electromagnetic field theory, later fully developed by J. C. Maxwell . Some of his works were collected as Experimental Researches in Electricity (3 vol., 1839–55) and Experimental Researches in Chemistry and Physics (1859).
