Founder of Faraday Law
In the world of electricity, many figures have participated. Call it de Coulomb, Alesandro Volta, Hans C. Cersted, and Andre Marie Ampere. They are considered the best "masters" in the field of electricity. However, from all of that, one must not forget a name that is very meritorious and is known as a pioneer in researching electricity and magnetism. He is Michael Faraday, a scientist from England.
Michael Faraday was born on September 22, 1791 in Newington Butts, England. His parents are classified as poor families. His father was only a blacksmith who had to feed his ten children. No wonder his father could not afford to pay for his children's schooling, including Faraday. To help the family economy, at the age of 14 Faraday worked as a bookbinder and bookseller. In between his work, he uses it to read various types of books, especially natural sciences, physics and chemistry.
When he was 20 years old, he attended lectures given by famous British scientists. One of them is Sir Humphry Davy, a chemist who is also the head of the Royal Institution laboratory. During his lecture, Faraday took careful notes and transcribed neatly back to what he heard. Then he sent the notes to Humphry Davy along with a job application. It turned out that the lecturer was interested and appointed Faraday as his assistant at the famous University Laboratory in London. At that time he was 21 years old.
Under Davy's tutelage, Faraday made rapid progress. Initially, he only worked as a bottle washer. However, thanks to his persistence in learning, in only a relatively short time, he was able to make new discoveries of his own creation, namely finding two chlorocarbon compounds and successfully liquefying chlorine gas and several other gases. Thanks to his cleverness, Faraday was able to connect with well-known experts, such as Andre Marie Ampere. In addition, he also had the opportunity to tour Europe with Davy. On this occasion, Faraday began to build on his practical and theoretical knowledge. Davy had a profound influence on Faraday's thinking and led Faraday on his discoveries.
Faraday's first important discovery in the field of electricity occurred in 1821. Two years earlier Oersted had discovered that the needle of an ordinary magnetic compass could be shifted if an electric current was applied in a wire that was not far apart. From these findings, Faraday concluded that when the magnet is tightened, the wire moves. Working on this conjecture, he succeeded in devising a clear scheme in which a wire would continuously rotate close to a magnet as long as an electric current was applied to the wire. In fact, in this case Faraday had invented the first electric motor, the first scheme of using an electric current to make an object move. However primitive, Faraday's invention is the "ancestor" of all the electric motors used in the world today. Since his first discovery in 1821, Michael Faraday, the self-taught scientist, became famous. The result of his discovery is considered to be the beginning of the study of electricity.
Faraday's Law
In experiments carried out in 1831, he discovered that when a magnet is passed through a piece of wire, a current will flow in the wire, while the magnet moves. This state is called "electromagnetic influence" and this discovery is called "Faraday's Law". This discovery is considered a monumental discovery.
Why? First, "Faraday's Law" has significance in relation to our theoretical understanding of electromagnetics. Second, electromagnetics can be used as a continuous propulsion of electric currents as used by Faraday in making the first electric dynamo. With his various findings, it is no exaggeration if Faraday is one of the figures who has made the greatest contribution to mankind. He is a simple person, an inventor who started learning on his own. He showed simplicity when he refused to be knighted and also refused to become chairman of the British Royal Society. Due to health problems, Michael Faraday stopped researching. However, he continued his work as a lecturer until 1861. He died on August 25, 1867 and was buried near the city of London, England.
