For this lab, we were testing Faraday’s Law which states that changing magnetic fluxes through coiled wired generate electricity. To test that law, we used a generator tube with a magnet that moves back and forth inside the coil of wire. This will show that the faster we shake the tube, the greater the generated voltage will be. The tube was connected to a NXT adaptor and motor which was connected to the computer program, Labview VI. The task was to relate the number of shakes in 30 seconds with the voltages that the generator produces.
In Excel, Labview recorded our voltages of each shake. After that, we had to square the voltages and take the sum of it to calculate the sum of the squares of the voltages.
The trials were difficult at first because the voltages would not match up with the number of shakes. It was also challenging to count the number of shakes when the person was shaking the generator tube really fast so the data might have been incorrect. It took a few trials to get the voltage and the number of shakes in a correct order.
