"Electricity and Magnetism" by Elsha Gray Elisha Gray was an American electrical engineer who co-founded the Western Electric Manufacturing Company. His expertise made him uniquely qualified to write a comprehensive book about his field. Electricity and Magnetism contains many examples of electromagnetic phenomena like induction, Hertzian waves, telluric currents, etc. All of these phenomena were used in a very ingenious way in various inventions without being able to have a theoretical explanation of their nature which Gray attempts to explain.
