My partner and I did the generator lab demonstrating Faraday’s Law that states that changing magnetic fluxes through coiled wires generate electricity. The greater the change in magnetic flux, the greater the currents and voltages. We used a flashlight shake generator to demonstrate this and are results were in accordance with Faraday’s Law.
To conduct the experiment my partner shook the tube for thirty seconds at a constant rate. She counted the the number of times she shook it and I recorded the number. Using excel, we took the sum of the square of the voltages and recorded that number. We repeated this four more times at different rates of shakes. Below are our results and a graph with a trend line representing what we learned from Faraday’s Law. The more shakes, the higher the sum of the square of the voltages.
