5K40.80 Genecon Motor/Generator
Electromagnetic induction, conservation of energy, Faraday's law, motors and generators, DC signal generation
The Genecon motor/generator is a motor or hand cranked DC generator that is used to drive another Genecon motor/generator and/or to light a series of LEDs. When the handle is turned, it rotates a loop of wire located between two permanent magnets inside the generator. As a result, there is a change of magnetic flux through the area enclosed by the loop with time, generating an EMF. Note: the aparatus is small but the handle motions and the lights are visible in a large lecture hall.
-  Genecon motor/generator (a handheld device that can be used as a motor or a generator)
-  Wire connector
-  Circuit board with LEDs
- The Genecon motor/generators are fragile. Handle with care.
To drive another motor/generator:
- Connect the leads of two Genecon motors/generators.
- Crank the 'generator' handle. The 'motor' handle will rotate.
- Hold on to the 'motor' handle. Notice that the 'generator' now requires more effort to crank.
To light a series of LEDs:
- Connect the motor/generator to the circuit.
- Turn the crank of the generator at a speed that lights up the LEDs.
- Turn the crank faster, notice that the brightness increases.
- Reverse the crank, showing directionality of the LED operation.
