Description

Reconstruction. In 1831, English chemist and physicist Michael Faraday (1791-1867) discovered electromagnetic induction, the manipulation of magnetism to make electricity. In the experiment shown here, a coil is connected to the battery (left) and to the iron induction ring (centre), creating a magnetic field. As the magnetic field forms, it induces an electrical current in the coil connected to the galvanometer (right), which shows the existence of the current with a swing of its pointer.
