What is that strange and mysterious force that pulls one magnet towards another, yet seems to operate through empty space? This is the elusive force of magnetism. In this Very Short Introduction Stephen J. Blundell considers early theories of magnetism, the discovery that Earth is a magnet, and the importance of magnetism in modern technology.

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.

Superconductivity is one of the most exciting areas of research in physics today. Outlining the history of its discovery, and the race to understand its many mysterious phenomena, this Very Short Introduction also explores the deep implications of the theory, and its potential to revolutionize the physics and technology of the future.

Professor Lee takes the reader through the early experiments and historical accomplishments, explaining principles behind such phenomena as magnetic behavior, paramagnetism and diamagnetism, ferrimagnetism, the earth's magnetism, and more. Over 60 graphic representations and 32 pages of photographs aid the author's fine exposition.

Introduces readers to the basic properties of light -reflection and refraction, polarization, and interference- before moving on to how light is generated, its role in relativity, and quantum effects it exhibits.

Known as the 'father' of electrical engineering, Michael Faraday is one of the best known scientific figures of all time. In this Very Short Introduction, Frank A.J.L James looks at Faraday's life and works, examining the institutional context in which he lived and worked, his scientific research, and his continuing legacy in science today.
