Magnetism is a strange force, mysteriously attracting one object to another apparently through empty space. It has been claimed as a great healer, with magnetic therapies being proposed over the centuries and still popular today. Why are its mysterious important to solve? In this Very Short Introduction, Stephen J. Blundell explains why. For centuries magnetism has been used for various exploits; through compasses it gave us
navigation and through motors, generators, and turbines it has given us power. Blundell explores our understanding of electricity and magnetism, from the work of Galvani, Ampere, Faraday, and Tesla, and goes on to
explore how Maxwell and Faraday's work led to the unification of electricity and magnetism, thought of as one of the most imaginative developments in theoretical physics. With a discussion of the relationship between magnetism and relativity, quantum magnetism, and its impact on computers and information storage, Blundell shows how magnetism has changed our fundamental understanding of the Universe. ABOUT THE SERIES: The Very Short Introductions
series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors
combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
This quite amazing book covers practically everything there is to know about magnetism. Ten seconds after opening the book, having scanned the contents section, I knew I was going to read not only about the birth of magnetism as a branch of scientific study, but also about Maxwells equations, relativity, quantum magnetism and technology. Two pages into the book, and I knew that the book was written in a relaxed, engaging, easy-to-follow style, which the author
maintains throughout. * Paul van Kampen, Dublin City University, Contemporary Science *
