Charging by Induction
... When the rod and the bal l come into contact, electrons pass into the positive side of the ball until it becomes negatively charged (see fig. d). Then the ball is repelled, of course, because it has a charge of the same sign as that of the rod. It follows that an induced charge is always the opposit ...

... The field is plotted below as a function of z. Let’s check two limiting cases. First, let z → 0 (or let R → ∞ with z fixed). This corresponds to a disk of infinite size, so we find the field of an infinite plane sheet of charge with uniform surface charge density. As z → 0, the last term in square b ...

Electrostatic generator
An electrostatic generator, or electrostatic machine, is an electromechanical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon, without a theory to explain its behavior and often confused with magnetism. By the end of the 17th Century, researchers had developed practical means of generating electricity by friction, but the development of electrostatic machines did not begin in earnest until the 18th century, when they became fundamental instruments in the studies about the new science of electricity. Electrostatic generators operate by using manual (or other) power to transform mechanical work into electric energy. Electrostatic generators develop electrostatic charges of opposite signs rendered to two conductors, using only electric forces, and work by using moving plates, drums, or belts to carry electric charge to a high potential electrode. The charge is generated by one of two methods: either the triboelectric effect (friction) or electrostatic induction.
