Quick Answer. Michael Faraday discovered the law of electromagnetic induction in 1831. He realized that current in a circuit can be induced by changing the magnetic field. Faraday tested it by wrapping a paper cylinder with a wire and connecting the coil to a galvanometer. Faraday then moved the magnet back and forth inside the cylinder.
Michael Faraday discovered benzene in the oily residue left behind from producing gas for lighting in London. 1831: Discovery of Electromagnetic Induction This was an enormously important discovery for the future of both science and technology. Faraday discovered that a varying magnetic field caused electricity to flow in an electric circuit. 1834: Faradayâs Laws of Electrolysis Faraday was one of the major players in the founding of the new science of electrochemistry. This is the science of understanding what happens at the interface of an electrode with an ionic substance.
