磁力、それは片方の磁力がもう一方を引きつける、奇妙でミステリアス、それでいて空間のすみずみで作用しているらしいもの…。磁力に関するファラデーやマクスウェルらの初期の理論をはじめ、地球が磁石だという発見や、恒星の磁場について明らかにします。磁気記憶媒体などの現代のテクノロジーに至るまで、磁力の重要性を考察します。
    

• Explains a fundamental scientific topic and its importance in an accessible way
• Considers early theories of magnetism including the discovery that the Earth itself is a magnet
• Explores the work of Michael Faraday and James Clerk Maxwell in unifying magnetism and electricity
• Looks at the quantum mechanical aspects of magnetism
• Considers its importance in modern technology, including magnetic storage in computers and the magnetic fields of planets and stars

 
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.
