Introduction:
Faradays law states that a changing magnetic feild through a coil of wire will generate electricity. Additionally, the greater the change, the more electricity will be produced.
Moving a magnet through a coil of wire produces an electric current.
Experiment:
In this lab, we tested this by shaking a tube which had a magnet inside a tube inside a coil of copper wire inside it. When the tube was shaken up and down, the magnet passed back and forth through the copper wire. The electricity produced was measured by the NXT and recorded in an excell sheet. To see how the amount of change affected the amount of electricity, we shook it at different rates and recorded the average electric current vs. the amount of shakes performed during the program’s run time.
The graph for the experiment, it shows the average voltage vs the number of shakes
Conclusion:
This lab proved Faradays Law. When the generator was shaken, it produced an electric current, and when it was shaken faster, the current was greater.
