There was a change in my original plan. On tuesday in class, it only took me about 10 minutes to finish the electromagnetic lab, and since my partner was not in class that day, I decided to go ahead and start the electricity generator lab. Then, on wednesday, instead of doing the second practice problem, I finished up the lab.
From the electricity generator lab, I learnt that when the speed of the bar magnet is increased, then it results in more voltage. From the data I could see that when the magnet was moving at 10 RPM, then there was barely any voltage at all. However, as it went to 30 RPM the voltameter started moving faster, and finally at 70 RPM, it was moving very fast. This is due to the fact that when the magnet is moving faster, it results in the electrons also moving back and forth faster. This results in the voltameter moving back and forth, which shows us more voltage.
