Michael Faraday 1791 - 1867 English scientist whose discoveries included principles of electromagnetic induction, diamagnetism and electrolysis. He is one of the most influential scientists in history, with little formal education, but brilliantly establishing the concept of the electromagnetic field in physics, induction and diamagnetism and the laws of electrolysis. He invented the electromagnetic rotary device as the foundation of electric motor technology. Faraday’s summaries, supported by equations, are accepted as the basis of all modern theories of electromagnetic phenomena. Faraday is one of the greatest scientific discoverers of all time”.
