Electricity generation: Build your own generator Activity Card

Students can build a simple generator of the type used in many wind turbines. Construction is simple, although it may be useful to provide some pre-wound coils for younger or less practically able students. It will also be useful to provide a small piece of wood for students to use as a winding jig. The activity could be extended by building some suitably sized rotor blades, attaching them to the rotor and seeing how the device performs in a windy environment.

After completing this activity students will:

  • Understand the basic principal of a generator.
  • Understand how the output of a generator can be increased.
