* When you rub a rod with nylon, you're transferring electrons. Nylon has a stronger attraction to electrons than many other materials, including common rods. This means it tends to "steal" electrons from the rod.
* The rod loses electrons, becoming positively charged. Since electrons carry a negative charge, removing them leaves the rod with a net positive charge.
* The nylon gains electrons, becoming negatively charged. The nylon gains the electrons the rod lost, giving it a net negative charge.
The result is that the rod and the nylon cloth will have opposite charges. This creates a static electric field between them. If you bring the rod close to another object, you might even see sparks jump between them!
Common examples of static electricity:
* Rubbing a balloon on your hair: The balloon becomes negatively charged and can stick to your hair (which becomes positively charged).
* Walking on a carpet in dry weather: Friction between your shoes and the carpet can create static electricity, causing a small shock when you touch a metal object.
