How Do Generators Work?

Discover how simple magnets and wires can be used to create electricity - and how this principle is now used in national power supplies. Physics - Electricity And Circuits - Learning Points. In 1835 the scientist Michael Faraday made an important discovery about magnetic fields and electricity. When a coil of conductive metal moves within a magnetic field an electrical charge will flow through it. Large generators produce gigawatts of electricity that provide the world with power. Changing the wire, speed, loops in the coil, and strength of the magnetic field will change the level of current. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.
