As soon as the motor began to spin and the water began to move around the tub, the propeller attached to the generator began to spin because of the water that was passing through it. As the propeller turned rapidly, the magnets began to spin, and generated a strong flow of electrons. This electrical current traveled through the wire and illuminated the light bulb. However, the motor that I had originally used was not powerful enough to generate a strong current, since I could only attach a small propeller to it. Therefore, I attached a larger propeller to my drill, and the current generated was able to power the light bulb more easily. When I measured the electrical current the magnets had created, 300mAmps were passing through the bulb.
