In fact, the dynamo is very simple. At the bottom there is a coil, which is a long copper wire on a bobbin. Above the coil there is a magnet. The magnet and the coil do not touch. |
||||
| A shaft connects the magnet to the driving wheel of the dynamo.So when the wheel is turning, so is the magnet.
Click the dynamo. |
||||
| When the magnet is turning over the coil electricity is generated in the coil. It is called electrical induction.
Maybe you have been wondering what a dynamo has to do with a wind turbine? |
||||
| A dynamo generates power and so does a wind turbine generator.
A dynamo and a generator are actually the same! Inside the generator there are also magnets moving over coils. Click the dynamo. |
