Hair and a balloon are rubbed together. A metal plate is brought close to the balloon, but they do not touch. I (a neutral and conductive human being) poke the metal and then go away. The metal plate is then brought over to a small metal ball hanging from a (insulating) string. After they touch the ball now repels from the plate.   Describe the motion of electrons through the step  by step process. Use correct  terminology if you know it, otherwise be very descriptive or use pictures to demonstrate what the electrons do. Is the small metal ball in the end positively or negatively charged?

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
