Miichaael ...Faraday?



Michael Faraday was an English natural philosopher in late 18th and early 19th centuries. Faraday was not considered a gentleman. Faraday, did however study the magnetic field around a conductor carrying a DC electric current, and established the basis for the magnetic field concept in physics. He discovered electromagnetic induction, diamagnetism, and laws of electrolysis. He established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena.

The SI unit of capacitance, the farad, is named after him, as is the Faraday constant, the charge on a mole of electrons. Faraday's law of induction states that a magnetic field changing in time creates a proportional electromotive force.

In 1845, Faraday discovered that many materials exhibit a weak repulsion from a magnetic field, a phenomenon he named diamagnetism. Faraday also found that the plane of polarisation of linearly polarised light can be rotated by the application of an external magnetic field aligned in the direction the light is moving. This is now termed the Faraday effect. He wrote in his notebook, "I have at last succeeded in illuminating a magnetic curve or line of force and in magnetising a ray of light". This established that magnetic force and light were related.

When Daniel Faraday first arrives on the island, he remarks on the unusual scattering of light on the island.



David Arthur Faraday was the first victim of the Zodiac (also the name of the raft) Killer in the 1960's.
