| Michael Faraday's Discovery |
| |
| In 1831, Michael Faraday discovered how to transform mechanical energy into continuous electrical energy by moving conductors through magnetic fields, thus laying the foundation for today's technological society. The Dynamo Flashlight is based on this discovery. |
| |
| The first dynamo was comprised of a rotatable copper disc placed between the poles of a horseshoe magnet. One wire of the current indicator (galvanometer) was connected to the axle of the disc, and the other was connected to a sliding contact on the edge. When the disc was rotated, the needle of the galvanometer moved in one direction and remained in that position as long as the disc whirled. |
