Faraday (Site not responding. Last check: ) |
 | | Faraday was one of four children, all of whom were hard put to get enough to eat, since their father was often ill and incapable of working steadily. |
 | | Faraday saw the "lines of force" thus revealed as lines of tension in the medium, namely air, surrounding the magnet, and he soon discovered the law determining the production of electric currents by magnets: the magnitude of the current was dependent upon the number of lines of force cut by the conductor in unit time. |
 | | Faraday took the suggestion, passed a beam of plane-polarized light through the optical glass of high refractive index that he had developed in the 1820s, and then turned on an electromagnet so that its lines of force ran parallel to the light ray. |
