  Faraday paradox - Wikipedia, the free encyclopedia
The Faraday paradox (or Faraday's paradox) is an experiment that illustrates the limitations of Michael Faraday's law of electromagnetic induction.
Faraday deduced this law in 1831, after inventing the first electromagnetic generator or dynamo, but was never satisfied with his own explanation of the paradox.
In Faraday's model of electromagnetic induction, a magnetic field consisted of imaginary lines of magnetic flux, similar to the lines that appear when iron filings are sprinkled on paper and held near a magnet.

Faraday was part of the party as Davy's scientific assistant, and was asked to act as Davy's valet until a replacement could be found in Paris.
Faraday also discovered the laws of electrolysis and popularized terminology such as anode, cathode, electrode, and ion, terms largely created by William Whewell.
Faraday, having discussed the problem with the two men, went on to build two devices to produce what he called electromagnetic rotation: a continuous circular motion from the circular magnetic force around a wire.

 Faraday paradox (electrochemistry) - Wikipedia, the free encyclopedia
The Faraday paradox was a once inexplicable aspect of the reaction between nitric acid and steel.
Around 1830, the English scientist Michael Faraday found that dilute nitric acid would attack steel, but concentrated nitric acid would not.
The key to resolving the paradox is passivation.

 Faraday's laws - Hutchinson encyclopedia article about Faraday's laws   (Site not responding. Last check: 2007-10-11)
English physicist and chemist Michael Faraday, one of the most prominent experimentalists of the 19th century.
Largely self-educated, Faraday is best known for his discoveries about the relationship between electricity and magnetism, published in the series Experimental Researches on Electricity (1839–55), which formed the basis of the theory of electromagnetic behaviour.
The laws of induction are: (1) a changing magnetic field induces an electromagnetic force in a conductor; (2) the electromagnetic force is proportional to the rate of change of the field; and (3) the direction of the induced electromagnetic force depends on the orientation of the field.

 Homopolar generator - Wikipedia, the free encyclopedia
Long after the original Faraday disc had been abandoned as a practical generator, a modified version combining the magnet and disc in a single rotating part (the rotor) was developed.
Before the discovery of the electron and the Lorentz force law, the phenomenon was inexplicable and was known as the Faraday paradox.
This law, discovered thirty years after Faraday's death, states that the force on an electron is proportional to the cross product of its velocity and the magnetic flux vector.

Unwisely, Faraday published his results without acknowledging his debt to Wollaston and Davy, and the resulting controversy caused Faraday to withdraw from electromagnetic research for several years.
Faraday's concept of lines of flux emanating from charged bodies and magnets provided a way to visualize electric and magnetic fields.
However his experimental work was consolidated by the able James Clerk Maxwell who developed his equations which lie at the base of all modern theories of electromagnetic phenomena.

Some background information on the homo-polar generator: 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.
Faraday's experiments led him to the revolutionary conclusion that a magnetic field is a property of space itself, not something attached to the magnet, which merely serves to induce or evoke the field.

 Faraday's disk
The principle of using a handle to make a smaller disk turn a bigger disk faster, as Faraday used it for the first dynamo, was of course widely used and could be found on a lot of objects, such as on the coffee mill on the picture to the right.
Faraday's disk is only made out of wood, which still leaves plenty of room for ornamentation for example on the wooden board (3), but as it is, the simplicity of the design suits the simplicity of the mechanical aspect, as unusual as this was in the 18th century.
Zénobe Gramme used the principle of Faraday's disk to design the first commercial power plants in Paris, discovering what is since then known as the basic concept of a spinning endless loop of wires.

 [No title]
It consists of a cylindrical conducting disk immersed in an axial magnetic field, and can be operated as a generator with sliding brushes extracting current from the voltage induced between the inner and outer regions of the disk when the rotational energy is supplied by an external driving source.
Faraday found, however, (Fig 7) that it does not matter whether the magnet itself is stationary or rotating with the disk as long as the conductor is moving in the field, but that rotating the magnet with the conducting disk stationary did not produce an induced voltage.
It was also well amalgamated, and then contact was made with this edge in different places by conductors formed from equally thick copper plate and with the extreme end edges grooved and amalgamated so as to fit on to and have contact with the edges of the plate.

By analogy, Faraday asserted that the particles of a non-conductor in an electric field would remain fixed in the polarized state and thus would not permit the transfer of charge.
Although Faraday well appreciated the similarities between magnetic and electrical phenomena, he considered pole to be a misleading name in the case of electrochemical cells and introduced the term 'electrode'.
This paradox is removed when the recommendation of Agar and Bowden is followed and the electrode behaviour is explained in terms of overpotentials.

 Science in Christian Perspective
Faraday, the great man of science, was also a devoutly religious man and a member of an obscure, small religious group, known as the Glasites or Sandemanians.
Faraday's religion was indeed, the very core and centre of the man, filling his whole life with power and peace, and embodying itself in all his actions.
It may seem paradoxical to some to find such a combination of characteristics in the life of one man. Perhaps because of this seeming paradox, some historians have sought to find in the life of Faraday something to suggest that his life as a scientist was in no way connected with his Christianity.

The paradox arises only when you put them together, and see that, although each of them appears to be internally true and consistent, when they are taken together at the same time, they destroy each other, losing their absolute truth.
Plato, in his dialogues on diverse questions, demonstrated the universal force of paradox: its methodological power and, at the same time, its formative force, which makes any interlocutor think; it is capable of setting any form of thinking and any mind, even the most inert, into motion.
We incorporate paradox into the content of the lessons, while simultaneously using it as a way of interacting with the children, regarding the content being conveyed to them.

 Circuit Analysis Accounts For Magnetic Fields
This introduction of Faraday's law into the circuit-analysis equations produces unexpected anomalies: Two voltages appear to coexist simultaneously between two nodes in a circuit, and the voltages appear to depend on position of the voltmeter leads.
The field varies with time, which induces current in the loop, and that condition calls for the use of Faraday's law: The integral of the tangential component of electric-field intensity around a closed loop equals the time rate-of-change for magnetic flux passing through a surface bounded by that loop (Eq.
Equation 11 is the extended Kirchhoff voltage law and equation 15 is the extended Ohm's law, with the sign of the dФ/dt term indicating the direction of current.

 Science: To Be, or Not to Be
Faraday reasoned that if Ampère’s conception were correct, the two cylinders should show the same magnetic effect; but his experiments showed that they behaved differently.
Ampère showed that Faraday did not understand the conception: the large circular windings of the solenoid are only macroscopic analogues of the very small circular currents hypothesized to reside within the atomic structure of the magnet.
It might, or might not, be relevant to the case at hand that, shortly after his discovery of the transverse current, which was accomplished in a thin layer of gold deposited on a glass plate, Hall discovered that iron produces a transverse current in the opposite direction.

The possibility of the existence of a nonlocal transference of specific stimuli, such as those that generate evoked potentials (electrophysiological brain responses produced by a sensory stimulus), was first studied by Grinberg-Zylberbaum et al (1978).
They observed that an evoked potential in a stimulated subject is "transferred" to another subject once they have interacted to achieve a level of "direct communication." This study was conducted in two Faraday chambers separated by a distance of approximately three meters.
The subject that stayed behind was now stimulated (generally by 100 light flashes given at random intervals), but the other subject was not stimulated, nor did he have knowledge that a stimulus was being received by the first subject.
