In class last week we again used our Lego Mind-storm robotics to perform an experiment, this one explored what electricity is and what it takes to generate it.  in order to generate electricity our class used flashlights which contained a magnet and a coil of wire.  When the flashlight was shaken the changing magnetic current created electricity.  The more the flashlight was shaken, the more electricity was made because of the shifting magnetic currents, this displacement of energy is what creates electricity.  The robot was hooked up to the flashlight generator, allowing my partner and I to record data about the amount of energy being created.  This information revealed that when the flashlight was vigorously shaken, it generated large amounts of electricity.  our results show that that more shakes meant more voltage being produced.

number of shakes:             25                             45                          75

electricity generated:          6.845715V          13.6106212V         39.415332V  

This diagram shows how electricity is generated, our experiment used a similar set up
