  Adventures in CyberSound: Faraday, Michael
Faraday expressed the electric current induced in the wire in terms of the number of lines of force that are cut by the wire.
Faraday's introduction of the concept of lines of force was rejected by most of the mathematical physicists of Europe, since they assumed that electric charges attract and repel one another, by action at a distance, making such lines unnecessary.
Faraday was part of this effort and on 3 and 4 September 1821 in his basement laboratory at the Royal Institution, he undertook a set of experiments which culminated in his discovery of electro-magnetic rotation - the principle behind the electric motor.

Faraday was one of four children, all of whom were hard put to get enough to eat, since their father was often ill and incapable of working steadily.
Faraday saw the "lines of force" thus revealed as lines of tension in the medium, namely air, surrounding the magnet, and he soon discovered the law determining the production of electric currents by magnets: the magnitude of the current was dependent upon the number of lines of force cut by the conductor in unit time.
Faraday took the suggestion, passed a beam of plane-polarized light through the optical glass of high refractive index that he had developed in the 1820s, and then turned on an electromagnet so that its lines of force ran parallel to the light ray.

Apart from the practical significance of this discovery, it was important as Faraday's interpretation of the phenomenon indicated that he was not a Newtonian in supposing that forces had to act rectilinearly.
Faraday also spent a considerable amount of time, especially in the early 1860s, working on various systems of electric light that were proposed.
During this period, Faraday pursued the consequence of his discovery of electro-magnetic induction, demonstrated the identity of electricities and revised entirely the theories of electro-chemistry (in the process coining now familiar words such as electrode, cathode and ion) and the nature of electricity.

He wrote a manual of practical chemistry that reveals his mastery of the technical aspects of his art, discovered a number of new organic compounds, among them benzene, and was the first to liquefy a "permanent" gas (i.e., one that was believed to be incapable of liquefaction).
Faraday began as Davy's laboratory assistant and learned chemistry at the elbow of one of the greatest practitioners of the day.
These experiments led directly to Faraday's two laws of electrochemistry: (1) The amount of a substance deposited on each electrode of an electrolytic cell is directly proportional to the quantity of electricity passed through the cell.

 Michael Faraday: The Invention of Faraday Cage   (Site not responding. Last check: )
Another explanation for the Faraday cage effect can be derived from Gauss's law that states that if there is no charge in a closed surface then the net flow of electric field from the surface must be zero.
To demonstrate his ideas, Faraday built in 1836 a room (the Faraday cage), coated with metal foil, and allowed high-voltage discharges from an electrostatic generator to strike the outside of the room.
The Faraday cage can be used to prevent the passage of electromagnetic waves and electric fields, either containing them in or excluding them from its interior space.

 Michael Faraday (1791-1867)
Similarly, because a magnetic pole tends to move in a circle around a current-carrying wire, Faraday argued that both electricity and magnetism occurred as a result of movements in a medium, rather than as a result of changes in currents and magnets.
Using this subtle distinction, Faraday displaced the efficient cause of electromagnetic force from currents and magnets to the medium between them, from which followed the insight that currents take time to propagate through a medium.
Faraday saw a medium where they saw nothing but distance: Faraday sought the seat of the phenomena in real actions going on in the medium, they were satisfied that they had found it in a power of action at a distance impressed on the electric fluids."
