This experiment focused on Faraday’s Law which states that changing magnetic fluxes through coiled wires generate electricity. Our goal in this experiment was to prove or disprove this statement, or to find a relationship between the number of shakes of the generator and the resulting voltage output.
Hypothesis: Faraday’s law is correct. As a matter of fact if you increased the frequency of the shakes, the output voltage would also increase.
In order to test this experiment we had a hand-held generator which we manually shook in order to produce electricity. We shook the generator at 3 different frequencies and monitored the voltage output with each. Using a computer program we were able to monitor the output compared to the number of shakes. Below are the results.
The results are clear. As we increased the frequency of shakes, the voltage output also increased. In our control experiment we didn’t shake the generator. It produced nearly no voltage output. When we increased the frequency to 29 shakes, the voltage increased by a minute amount. In our last experiment we increased the number of shakes to 68 and the increase in voltage output was incredible. The computer program registered nearly a voltage of nearly 75.32. This proves Faraday’s law because as the generator was shaken, the magnet went through the coils and did in fact produce electricity.
Fun Fact: Faraday’s law is used now a days in things as simple as flashlights. In order to save battery use, companies have developed flashlights that work just like the generators were using. The battery is charged by shaking the flashlight. The shaking movement causes a magnet to travel between a coil and electricity is created.
If we shake with more strengh, is the voltage affected ?
I loved your fun fact it was very informative
