disk dynamo

What is a dynamo? A dynamo, also called an electric generator, is simply a machine that converts mechanical energy into electricity. Dynamos are most often found inside power plants. They generate the electricity you need to heat your house, to watch TV, to listen to your radio etc. The mechanical energy that powers the dynamo may be obtained from various sources as for example, wind turbines, water turbines at dams, and steam turbines. How does it work? The simplest of all the dynamos is the disk dynamo developed by Michael Faraday (1791-1867). It consists of a copper disk mounted so that part of the disk, from the center to the edge, is between the poles of a horseshoe magnet .
