Why did you build your generator the way you did? I built my generator the way I did because I knew that the generator would produce electric current by rotating a loop of wire in a magnetic field. When connected to a source of mechanical energy and placed between poles of a magnet it rotates, and an electric current is produced. Mechanical energy is then transformed into electrical energy. 2. Which object do you think your generator will power? Why? I think all my objects will be powered on because I used the equation V=CBNR. 3. What were the results of your test? (Success/Failure) My results were a success. The first time I tried with the flashlight was by chance I had it right. I was taking into account each item had a voltage printed on the direct object and working out calculations. Technically, the Cd player was a fail at the beginning until I changed the number of turns of spin in the wire to make it accurate. The keyboard was also a success from the start. 4. What would have happened if you had chosen a different magnet? More coils of wire? A different speed? If I had chosen a different magnet, more coils of wire or a different speed it could put out a different voltage. When electricity moves through the wire coils heat is then produced. If you increase the magnetic field or if the magnet was rotated faster the voltage would also increase. Everything is affected differently when more/less wire or speed is entered into the equation. Different factors equal to different outcomes. ...
