Michael Faraday


Born into a poor family at age thirteen Michael Faraday became an errand boy for book binding. Every book that he bound he read, soon becoming interested in the concept of energy, specifically force. A couple of years later when he was older he applied to Humphry Davy for a job, becoming his temporary assistant. For eighteen months he spent those days touring during Davy’s investigations into his theory of volcanic action. Davy gave Faraday a valuable scientific education also he introduc3ed him to important scientists in Europe. Another couple years after when Davy retired, Faraday replaced him as a professor of chemistry at the Royal Institution.

          Michael Faraday was an English chemist and physicist. He was best known for his work with electricity and magnetism. He built two devices to produce what he called electromagnetic rotation, which is a continuous circular motion from the circular magnetic force around a wire. Faraday also discovered that magneto-electric induction is the production of a steady electric current. His biggest break through was the invention of the electric motor. In 1831another discovery of electromagnetic induction, this is the induction of generation of electricity in a wire by means of the electromagnetic effect of a current in another wire. Also in 1831, he made the first dynamo. In 1832, he proved that the electricity induced from a magnet, voltaic electricity produced by a battery, and static electricity. In 1837 Faraday demonstrated that electrostatic force consists of a field of curved lines of force, conceived a specific inductive capacity. This led him to be able to develop his theories on light and gravitational systems.

           Michael Faraday had a law and it was the law of induction, which is a basic law of electromagnetism relating to the operating principles of transformers, inductors, and many types of electrical motors and generators. His law states that: the induced electromotive force (EMF) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit. Alternatively the EMF generated is proportional to the rate of change of the magnetic flux.

          When the military asked him to help and develop poison gases to be used in the Crimean War he refused. He did not want to be a part of any war. Government recognized his contribution to science by granting him pension and giving him a house. Faraday published details of his research including condensation of gases, optical deceptions and the isolation of benzene from gas oils. He was also the author of several books including Experimental Researches in Electricity and Chemical History of the Candle. Michael Faraday’s greatest contribution to science was in the field of electricity.
