Shake Generator Lab

In class, we did an experiment revolving around Faraday’s Law. This law states that changing magnetic fluxes through coiled wires generates electricity. The larger the change in magnetic flux, the more electricity that will be produced.

Since the magnet passing through the coils is what produces the electricity, then how many times the magnet passes through the coils would determine would determine how much us produced. In theory, the more times the magnet passes through, meaning faster shakes would mean more electricity, while the less times it passes through due to slower shakes would mean less electricity.

From this, the independent variable would be the “shakes” while the dependent variable would be  the level of electricity produced.

The control would be no shakes, so that there is a baseline to work off of, From here, set paces for shakes would be determined, while the number of times the “generator” is shaken.  In this case the generator is a shake light.

Here are the results:

From looking at these results, there are some issues to be seen. This can be a result from several things, which would be human and equipment error.

The human error would be that the shaking is done by human hands, and isn’t precise in shaking at an exact speed. As for equipment, the electricity is measured at certain points, but that doesn’t mean it measures it when the magnet is passing the coils, when the change in magnetic flux is happening. As a result, nothing is perfectly done, but nevertheless, a clear picture is made.

There is a positive correlation. As the amount of shakes increases, so does the electricity for the most part. While this experiment wasn’t without it’s faults, it does answer the question of whether more shakes means more electricity.

  1. Clearly written and easy to follow blog! I found it interesting that from 18 shakes to 40 shakes the voltage actually decreased rather than increasing. I am glad that you address some possible reasons for this and the other issues with your results. Overall, great blog!
