Our last class experiment was about generating energy. We used a flashlight that had a magnet and coiled wire inside of it.
We learned that the faster we shook the flashlight, the more energy we created. When the flashlight was connected to the computer, we could calculate how much energy was created.
We shook the flashlight slowly and then started increasing how fast we moved the magnet inside. The computer calculated how much voltage was created when we shook the flashlight and we put the information into a graph.
