In order to fully understand this experiment you should first learn about Faraday’s Law.
Faraday’s Law states that any change in the magnetic environment of a coil of wire will cause a voltage (emf) to be “induced” in the coil. No matter how the change is produced, the voltage will be generated.
Our equipment included:
- One generator
- One voltage probe
- One NXT adaptor
- NXT
- Labview VI
With these materials, and the Faraday’s law in mind, we started the experiment. Our goal for this experiment was to compare the number of shakes of the generator, in a thirty second time interval, with the voltages that the generator generates. After a bit of a technically difficulties, we were able to record the correct numbers and square them all and find the sum. After about four trials, we complied the information and made a graph to better understand our results. Attached you will find our excel chart with our numbers.
