Charging Materials
- Certain insulating materials can become charged. You can charge certain insulating materials by rubbing them together. For example, if you rub together an uncharged plastic rod with an uncharged cloth, both will get charged.
- Electrons can move from rod to cloth. Electrons are negatively charged particles, which move from the rod to the cloth during rubbing. Protons, which are positively charged particles, never move. The rod becomes positively charged as it loses electrons. The cloth becomes negatively charged as it gains electrons.
