Michael Faraday



This century the century of electricity. Indeed, some say space age, some say the atomic age, but all of this - however the importance of - relatively little impact to everyday life. Another case with electricity. Seemed unimaginable a good way of life could be without electricity. Incessantly from morning to morning we took advantage of electricity. The fact is, no type of technology is so widely spread than the use of electricity.
Many contributors in terms of electricity: Charles Augustine de Coulomb, Count Alessandro Volta, Hans Christian Oersted and Andre Marie Ampere. They-they-are among the candidate best candidate in the field of electricity. However, the peak bin is the culmination of all the British scientist Michael Faraday and James Clerk Maxwell. Although the two men work related to each other and complement each other-complete, but they are not located in one team, each creating a personal, because it can both honored place in the list order this book.
Michael Faraday was born in 1791 in Newington, England. Origin of the haves and the family was generally taught myself. At the age of fourteen he became an apprentice carpenter volumes and selling books, and he used this opportunity many people read books like crazy. When age stepped twenty years, he visited the lectures given by renowned British scientist Sir Humphry Davy. Faraday was fascinated and gaped open. Davy wrote a letter to the short story and a good profit received 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.
Faraday's discovery of the first importance in the field of electricity occurred in 1821. Oersted two years earlier had found that the magnetic compass needle always be shifted if an electric current flows in the wire that is not far away. This make Faraday concluded, if the magnetic diketatkan, which moved just wires. Working on the basis of this allegation, he managed to make a clear scheme where the wire will continually rotating magnet near an electric current flows along the wire. Indeed in this case Faraday had discovered the first electric motor, a first scheme using an electric current to make an object move. No matter how primitive, this Faraday discovery is "ancestors" of all electric motors are used the world today.
This is opening extraordinary way. However, its practical usefulness is limited utility, as long as there is no method to drive electric current from the battery than a simple chemical at the time.Faraday sure there must be a way of using magnets to move the electricity, and he kept looking for a way how to find the method. Today, magnets are not moving does not affect the electric current adjacent to the wire. But in the year 1831, Faraday discovered that when the magnet passed through a wire, current will flow in the wire while the magnet moves. This condition is called "electro-magnetic effects," and this discovery is called "Faraday's Law" and is generally considered the most important discoveries and Faraday's largest.
This is a monumental discovery, by two reasons. First, "Faraday's Law" has a fundamental importance in relation to our theoretical understanding of the electro-magnetic. Second, electro magnetic can be used to drive continuous flow of electricity as demonstrated by Faraday's own production through the first electric dynamo. Although the energy generators of our power plants to supply the city and the factory today is much more perfect than what was done Faraday, but all based on similar principles of electro magnetic influence.
Faraday also contributes in the field of chemistry. He made a plan to change a liquid gas, he found various types of chemicals, including benzene. The work is more important is the effort in the field of electro-chemical (chemical investigation of the effects of electrical current). Faraday investigation with high precision to produce two laws "elektrolysis" a reference to his name coupled with that is the basis of electro-chemistry. He also popularized the many terms used in the field such as: anode, cathode, electrode and ions.
And is likewise Faraday who introduced into the world of physics important ideas about the magnetic lines and electric power lines. With the emphasis that was not his own magnetic field but in between, he helped prepare the way for progress in various fields of modern physics, including Maxwell's statement about the similarities between the two expressions through signs (=) as 2x 5 = 10. Faraday also discovered, if the combination of two light is passed through a magnetic field, will experience a change perpaduannya. These findings have special significance, because this is the first clue that there is a relationship between light with magnets.
Faraday not only intelligent but also beautiful and had a style as a speaker. But he simply could not take the matter in terms of fame, money and flattery. He refused was knighted and also refused to become chairman of the British Royal Society. Live long and happy marriage, just do not have kids. He died in 1867 near the city of London.
