Michael Faraday

The British scientist Michael Faraday discovered a means of generating electricity as early as the 1820s. | He moved a loop or disc of conductive metal between the poles of a magnet. | The basic principle is that electrons in copper wire are free to move. | In other words, the electric field surrounding a charged particle exerts a force on other charged particles, causing it to move and thus do work. | Each electron carries a negative electrical charge. Its movement is governed by attractive forces between the electron and positive charges and repulsive forces between the electron and like-charges.
