Michael Faraday and electromagnetism

Michael Faraday was a prestigious British physicist and chemist who was born on September 22, 1791 and died on August 25, 1867. He dedicated his career to the study of electromagnetism and electrochemistry.

After attending different conferences on chemistry held by the famous chemist Sir Humphry Davy at the Royal Institution, Faraday requested to work as an assistant in his laboratory. Thus, when one of Davy's assistants left his post, he was offered by Michel Faraday, who became his disciple.

In a short time, Faraday began to stand out in the field of chemistry, making numerous discoveries such as benzene or the first known reactions of organic substitution, thus obtaining chlorinated compounds of carbonated chain starting from the use of ethylene.

During that same time, magnetic fields generated by electric currents were discovered by Danish scientist Hans Christian Oersted. Thus, based on this discovery, Michel Faraday developed the world's first electric motor.

Later, in 1831 he investigated the phenomena of electromagnetic induction in collaboration with Charles Wheatstone, observing the electric current produced by a moving magnet through a coil. With this, he was able to describe mathematically what is the law that governs the production of electricity by a magnet.

Continuing with his electromagnetic studies, Faraday also discovered what is known as the "Faraday effect" in 1945, which consists in the deviation of the polarization plane produced by light, as a consequence of a magnetic field when it crossed a transparent material such as glass. This was the first known case of interaction between light and magnetism.

In this way, Michel Faraday was one of the most prominent physicists of the nineteenth century, whose work was essential for the development of later physics, as is the case of the electromagnetic field theory developed by James Clerk Maxwell.
