He similarly discovered the principles of electromagnetic induction, diamagnetism, and the laws of electrolysis. Faraday also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena. It was by his research on the magnetic field around a conductor carrying a direct current that Faraday established the concept of the electromagnetic field in physics. Although Faraday received little formal education, as a self-made man, he was one of the most influential scientists in history. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis.
Michael Faraday FRS ( / ˈ f ær ə d eɪ, - d i/ 22 September 1791 – 25 August 1867) was an English scientist who contributed to the study of electromagnetism and electrochemistry.
