The goal of this lab was to explore the relationship between magnetic fluxes and current. This relationship is based in Faraday’s law that states that the changing magnetic fluxes through coiled wires generates electricity. The increase in magnetic flux generates more electricity. In this experiment we explored these two variables to produce energy.
on a very basic level, we show how generators work because they are based on Faraday’s law as well. my partner and I attached our robot to the computer to receive our data then connected red and black wires to a flashlight with coiled wire on the inside. We shook the flash light at varying speeds for 30 second intervals .We counted how many shakes each time we ran the experiment. This action moved the magnet inside the coils to produce electricity like in Faraday’s law.
After each 30 second interval of shaking we now looked at our data points and squared each data point we had for voltages then added them all to receive a data points.
| # of Shakes | Sum of the square of the voltages | |||
| 16 | 0.74 | |||
| 18 | 41 | |||
| 32 | 108 | |||
| 62 | 404 | |||
| 145 | 404 | |||
After getting each of these points by running the experiment 5 times we plotted our data according to how many shakes on the x axis and amount of voltages on the y axis. An upward trend is shown between the amount of voltages and the number of shakes proving Faraday’s law that the increase in magnetic flux, or the amount we shake correlates to how much electricity is being outputted.
