		Although the Faraday effect is not itself chromatic, the verdet constant itself is quite strongly a function of wavelength.
		Faraday Isolators are passive unidirectional, non reciprocal devices that utilize the phenomenon of Magneto-Optic Rotation to isolate the source from reflections in an optical system.
		Faraday Rotators are also used for example in ring laser systems to introduce a loss mechanism (in conjunction with some other intra-cavity polarization selective element) which is greater for one direction of propagation than for the other.

	Michael Faraday Summary
		Faraday was devoted to the idea of communicating science to the public and for close to forty years his very popular lectures brought experimental and theoretical physical science to a broad audience.
		In 1834 Faraday developed his two laws of electrochemistry, which claimed that the amount of chemical activity in matter is directly proportional to the amount of electricity passed through the matter, and that the masses of matter produced from an electrochemical reaction are proportional to their chemical equivalents.
		Faraday's geometric-intuitive representation was in particular rejected by the Continental electrodynamicists, and in 1846 Wilhelm Weber developed a theory of forces acting directly at a distance between charges that included the phenomena of electromagnetic induction.

	Theories and Laws of physics
		Faraday's second law of electrolysis The charge Q equired to deposit or liberate a mass m is proportional to the charge z of the ion, the mass, and inversely proprtional to the relative ionic mass M; mathematically, Q = F m z/M. Faraday's laws of electromagnetic induction (M. Faraday)
		Faraday's second law of electromagnetic induction The magnitude of the electromotive force is proportional to the rate of change of the field.
		The constant of that proportionality is the Young modulus of elasticity for that substance.

	Michael Faraday pioneer scientist
		Faraday has the international unit for capacitance named after him, the Farad, marking his distinguished work with dielectrics; and also a physical constant, the Faraday Constant.
		The `Faraday dark space', observed with electrical discharges in gases (for example, as in fluorescent tubes), pays tribute to him, and the `Faraday effect' in magneto-optics was one of his triumphs later in his career.
		Faraday had a profound sense of the fallibility of man. This undoubtedly derived from reading the Bible with understanding, but two specific influences might also be identified.

	Faraday constant (Site not responding. Last check: 2007-10-08)
		In electrolysis, Michael Faraday in 1832 - 1833 discovered the relationship between the charge and the quantity of matter liberated in an electrode reaction.
		The number of faradays that must pass through a circuit when one mole of a substance is produced or consumed is a whole number.
		That one mole of atoms or molecules always requires an integral number of faradays suggests a once novel but now familiar idea: the existence of a natural unit of charge, the charge of an electron.

	Faraday's Law
		Faraday's law is a fundamental relationship which comes from Maxwell's equations.
		It serves as a succinct summary of the ways a voltage (or emf) may be generated by a changing magnetic environment.
		When an emf is generated by a change in magnetic flux according to Faraday's Law, the polarity of the induced emf is such that it produces a current whose magnetic field opposes the change which produces it.

	faraday
		In terms of Michael Faraday's experiments, 1 faraday of charge will deposit on the negatively-charged electrode 1 mole of silver (since silver ions are single ionized), or ½ mole of copper (since copper ions are doubly ionized), or 1/3 mole of aluminum.
		The Faraday constant is a ratio of charge in coulombs to amount of substance, singly charged, in moles.
		In biochemical studies of ion transport across membranes, the Faraday constant is defined as the number of calories released as one mole of ions moves down a voltage gradient of 1 volt, about 23062 calories/mole/equivalent.

	Notes on the Faraday Disc
		The Faraday Disc [reference 1] is generally thought to be a two piece machine consisting of a conducting disc rotating proximate to the north or south pole of an axially suspended fixed magnet.
		The true discovery of Faraday was that relative motion was not necessary for the generation of electricity.
		In the Faraday disc, the torque is relative to the reference frame of the instrumentality which is the evocateur of the magnetic field.

	Michael Faraday - Wikipedia, the free encyclopedia
		Note that Faraday did not have a tertiary education, however Humphry Davy is considered to be the equivalent of his doctoral advisor in terms of academic mentorship.
		Faraday was a devout Christian and a member of the small Sandemanian denomination, an offshoot of the Church of Scotland.
		Faraday used "static", batteries, and "animal electricity" to produce the phenomena of electrostatic attraction, electrolysis, magnetism, etc. He concluded that, contrary to scientific opinion of the time, the divisions between the various "kinds" of electricity were illusory.

		The value of the fundamental constant e is then calculated from many observations on different drops and knowledge of other relevant quantities, especially the viscosity (resistance to flow) of the air.
		Millikan had taken a value that was almost entirely based on a measurement by one of his students; but it was later shown that the student had made a rather subtle experimental error.
		Although this case is an example of the general fact that the experimentally determined value of a constant varies with each determination, it must be realized that it is just these variations from determination to determination in the measured numerical values of the constants that often furnish important clues to errors in experiment and theory.

	Fiber Optic Wheel Sensor
		The proportionality constant for Faraday rotation, the Verdet constant, is a property of the crystal material, but it is particularly large for a class of materials known as iron-garnets.
		Furthermore, the Faraday effect in iron garnets saturates at large fields, so that the crystal can be made to produce not more than 90 degrees of total rotation at saturation to ensure that the transmitted signal is a monotonic function of the field.
		Since the Faraday rotation depends on the component of the optical path along the magnetic field direction, all the light is rotated by the same angle, whether or not it has been diffracted, so long as the field is uniform over the crystal dimensions.

		Michael Faraday reported that passing electricity through one solution liberated 1 mass of hydrogen at the cathode and 8 masses of oxygen at the anode.
		According to Faraday’s laws, the amount of substance produced or consumed in electrolysis is proportional to the amount of electricity that passes through the cell.
		The electrical charge on one mole of electrons is called the Faraday’s constant and is generally expressed in Coulombs per mole of electrons (96,485.31 Coulombs/mole of electrons).

	Electrolytic Cells
		The amount of a substance consumed or produced at one of the electrodes in an electrolytic cell is directly proportional to the amount of electricity that passes through the cell.
		Example: To illustrate how Faraday's law can be used, let's calculate the number of grams of sodium metal that will form at the cathode when a 10.0-amp current is passed through molten sodium chloride for a period of 4.00 hours.
		This bridge is represented by Faraday's constant, which describes the number of coulombs of charge carried by a mole of electrons.

	Faraday constant - a definition from Whatis.com
		The Faraday constant represents the amount of electric charge carried by a one mole, or Avogadro's number, of electrons.
		It is an important constant in chemistry, physics, and electronics, and is commonly symbolized by the italic uppercase letter F.
		The Faraday constant can be derived by dividing the Avogadro Constant, or the number of electrons per mole, by the number of electrons per coulomb.

	20929. Researching Faraday's Law [England]
		I am doing my GCSE course work for chemistry and I wanted to know EXACTLY what Faraday's Law and Faradays constant IS? word for word in a discription and formulae so that I can understand it.
		It should also be intuitive that there is some relationship between this number and Avagadro's constant, and there is. Avagadro says there are 6.02e23 electrons per mole.
		So, in electroplating, for every mole of electrons you move through your external wired circuit, that many moles of metal will be oxidized at the anode, migrate through the solution, and be reduced upon the cathode.
