This small generator (Dynamo)may be mounted on a bicycle to produce electricity. The turning tires will turn the head of the generator and it will produce electricity that is accessible from the bottom contact.
Electricity produced by this generator can be used to light up multiple light bulbs.
This small generator can also be used for science projects related to converting wind energy or other types of mechanical energy to electrical energy.
Students can make their own wind turbine, water wheel or any other source of mechanical energy and use a wheel or belt to transmit such energy to this generator and produce 6 Volts, 3 watts energy.
