Michael Faraday was born in 1791 in Newington, England, noted as the first inventor of the dynamo, i the age of fourteen he was an apprentice so builders volumes and selling books, and he used this opportunity many people read books like crazy. When stepping age twenty, he visited the lectures given by renowned British scientist Sir Humphry Davy. Faraday was fascinated and gaping-gaping. He wrote a letter to Davy and short stories lady luck accepted as his assistant. Within a few years, Faraday was able to make new discoveries on the results of his own creation. Although he did not have sufficient background in mathematics, as a natural scientist he was unchallenged.
Faraday first important discovery in the field of electricity occurred in 1821. Oersted two years earlier had found that the magnetic needle compass can be shifted if the normal electrical current flowed in the wire are not far apart. These make Faraday concluded, if the magnet diketatkan, moving it wires. Working on the basis of these allegations, he managed to make a clear scheme where the wire will constantly rotating magnet adjacent to all electrical power is applied to the wire. Indeed, in this case the Faraday had discovered the first electric motor, a first scheme uses an electric current to create something moving objects. No matter how primitive, Faraday's discovery of an "ancestor" of all electric motors used today's world.
This is an outstanding pacesetter. However, its practical usefulness is limited utility, as long as there is a method to drive electric current from the battery chemistry than simple at the time. Faraday sure, there must be a way of using magnets for electric drive, and he's constantly looking for a way how to find the method. Now, the magnetic sedentary does not affect the electric current adjacent to the wire. But in 1831, Faraday discovered that when a magnet passed through a piece of wire, current will flow in the wire while the magnet moves. This is called "electro magnetic influence," and this is called a "Faraday's law" and is generally considered the most important discoveries of Faraday and greatest.
This is a monumental discovery, for two reasons. First, the "Faraday's law" has a fundamental importance in relation to our theoretical understanding of electro-magnetic. Secondly, electro magnetic can be used to drive continuous electric current as demonstrated by the Faraday through manufacturing the first electric dynamo. Although the power generator to supply power our cities and factories today is much more perfect than what is done Faraday, but all based on a similar principle to the effect of electro-magnetic.
Faraday also contributed in the field of chemistry. He made a plan to change the gas so fluid, she finds various types of chemicals, including benzene. More importantly, the work of his efforts in the field of electro chemistry (chemical investigation due to electrical current). Faraday investigation with great precision to produce two laws "elektrolysis" which penyebutannya coupled with his name which is the basis of the electro chemistry. He also popularized a lot of the terms used in the field such as anode, cathode, electrode, and ion.
