Michael Faraday (1791–1867) was the greatest physicist of the 19th century, a pioneer in the fields of electricity and magnetism. He is best known for his discovery of the principle of electromagnetic induction and the laws of electrolysis. In Experimental Researches in Electricity, first published in three volumes between 1839 and 1855, Faraday discusses the inquiries that led to his development of the first dynamo (the precursor of modern dynamos and generators), and his establishment of the foundations of classical field theory. His descriptions contain scarcely a word of mathematics, and he relates the progress of his experiments in direct, clear language. 1914 ed. 80 figures.
