Our task for this lab was to shake the hand powered generator (a tube with a magnet in it) in order to correlate the number of shakes, with the time interval, and the voltage. We shook the generator for thirty seconds at a specific rate five times. Each time we had to count the number of shakes and the computer program calculated the voltage after each second. We then calculated the sum of the squares of the voltages and plotted them in a graph to see the correlation which resulted in a linear curve.
The higher the number of shakes in the thirty second interval the higher the sum of the square of the voltages. The two are correlated in a linear way, in which as one increases so does the other. This experiment supports Faraday’s law that the greater the change in the magnetic flux the greater the voltages created.
