Faraday's electromagnetic induction apparatus, 1831.
© Science Museum / Science & Society Picture Library
Replica of apparatus used by Michael Faraday (1791-1867), the English chemist and physicist, for producing induced currents by plunging a magnet into a solenoid. Electromagnetic induction is the use of magnets to produce electric current. Faraday's great life work was the series 'Experimental Researches on Electricity' published over 40 years in 'Philosophical Transactions', in which he described his many discoveries, including electromagnetic induction (1831), the laws of electrolysis (1833) and the rotation of polarised light by magnetism (1845).
