	Electrostatic induction - Wikipedia, the free encyclopedia
		Electrostatic induction is a method by which an electrically charged object can be used to create an electrical charge in a second object, without contact between the two objects.
		The effect can be demonstrated using an electroscope, which is an instrument for detecting electric charge.
		Numerous electrical generators and electrostatic generators, such as the Wimshurst machine, the Van de Graaff generator and the electrophorus, rely on this principle.

		These operate by electrostatic induction and convert mechanical work into electrostatic energy by the aid of a small initial charge which is continually being replenished or reinforced.
		The charges thus deposited on the glass disk are carried round so that the upper half is electrified negatively on both sides and the lower half positively on both sides, the sign of the electrification being reversed as the disk passes between the combs and the armature by discharges issuing from them respectively.
		It was an electrostatic and electromagnetic machine combined, driven by an electric current and producing in turn electrostatic charges of electricity.

	electromagnetic induction and inertia
		However the calculation was made for a radial electrostatic field (albeit on the working assumption that the electron could be modelled by this) and hence the proper conclusion is that a radial electrostatic field violates relativity.
		Electrostatic and magnetostatic fields exhibit inertial properties, but it is fair to say that there are issues awaiting resolution.
		Electrostatic inertia is associated with the concept of inductance, used in electric circuits; creating the magnetic field in an inductor takes energy that must be supplied by the external electromotive source.

	Induction: What It Means to ESD
		In this article, we'll discuss induction in its two forms and examine a series of practical examples which point to the fact that induction is a subject relevant to and worthy of ESD investigation.
		But if the charged material binds by induction a charge of just 1 mC on the operator, the operator will carry about 5000 V and be able to dissipate an energy in his environment of about 2 mJ, or 10 times the minimum ignition energy for most mixtures of organic vapors with atmospheric air.
		The operator will, by induction, be charged to a voltage (although the operator's total charge may be zero), and if this person then touches a grounded component the resulting current pulse may destroy the component.

	induction, in electricity and magnetism. The Columbia Encyclopedia, Sixth Edition. 2001-05
		Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is the most important of the three phenomena.
		Changing the current in a given circuit can also induce an emf in another, nearby circuit unconnected with the original circuit; this type of electromagnetic induction, called mutual induction, is the basis of the transformer.
		Electrostatic induction is the production of an unbalanced electric charge on an uncharged metallic body as a result of a charged body being brought near it without touching it.

		The dilninu- tion of inductive effect produced when a plate of metal or a spare wire is placed between the wires carrying the inducing and induced currents was found to be much greater than with the foil, and also greater with the overtones of the sounds transmitted than with the fun- damental.
		That electrostatic induction is alnost in- effective, so far as producing sounds in the receiving telephone is concerned, is shown by the fact that if a small secondary coil with a large and deep primary is held at right angles to its plane.
		If intermittent or variable currents are passed through a coil of wire forming a closed circuit, within which a second closed parallel coil is placed, the sec- ondaly current induced in the latter can be investigated to a certain extent by inserting a receiving telephone in the secondary circuit.

	The Van de Graaff generator
		The Van de Graaff electrostatic generator is an 'addition' electrostatic machine: charges are added to a conductor by a movable carrier.
		These apparatus, which in fact were induction electrostatic machines,represented fundamentally a mechanised version of Volta's perpetual electrophorus of 1775 (10).With these apparatus very small charges, to weak to be detected by a common electrometer, were 'multiplied' by electrostatic induction until they could be measured.
		Ion sources, particle injection and particle beam handling, vacuum (for the accelerating tube) and pressure equipment (for the tank), control and measurement instruments, etc., form a very complex array of apparatus typical of 'big science' equipment, for which the interchange of ideas between scientist and engineers proved to be particularly fruitful.
