To explore magnetic energy, we built a battery charger that spins a magnet to generate the electricity needed to charge a AA battery. We also made a Faraday cage, which is a structure covered in any conductive metal that blocks radio and magnetic waves. This is a very important aspect aspect because inside the car, the driver is surrounded by magnets, which means if they had any electronics, such as their cell phone, with them in the car, the electronics would be ruined.
