Hi, I'm still confused on how a Van de Graaf generator works We did a lab involving it and my observation is as listed: Rubber band: the rubber band would stick for a short while, but then would bounce off momentarily, and would repeat this process. Paper clip with string: The paper clip seem to repell when near the generator. Part of the string would stick to the generator, but some part of the string also seem to repell and float in air. Plastic ruler: no change Here's what I think is happening. The van de graf creates a huge electric field with points away from the generator. Induction would take place. Materials that are conductors allow the electrons to move around inside the material, which allow them to react with the generator. Non conductors such as the plastic ruler does not react. Do I have the right idea? Can someone guide me through this?
