In this lab, we tested how Faraday’s Law of magnetic flux affects the generation of electricity. Our tool used to generate a varying magnetic flux.was a modified flashlight that creates a charge by shaking a magnet inside the flashlight past copper wires. Rather than using this energy to power a light bulb like a normal flashlight, the charge was led through two wires and into our NXT robot, which recorded the voltage created through a LabView program and wrote the results to an Excel document. We were to test how changing the shake rate of the flashlight affected the output of energy. It was hypothesized within our group that as we shook the flashlight more intensely, the amount of electrical voltage created would increase.

We ran three trials with the flashlight. First, we let the flashlight sit still without any shaking. Second, we shook the flashlight about 25 times at a medium intensity, and finally we shook the flashlight about 50 times at a very high intensity and then calculated the sum of the voltages recorded within Excel. The results were reflected in the following graph:

The results show that what we predicted turned out to be true. When we didn’t shake the flashlight, almost no voltage was recorded. As we increased the number of shakes, the voltage produced by the flashlight also increased. The results were also pleasantly consistent, as seen by the trend line within the graph.

The relevance of this experiment was to show that Faraday’s Law correctly demonstrates how increasing magnetic flux also increases the amount of electric voltage produced.
