Electricity and Magnetism is a standard textbook in electromagnetism originally written by Nobel laureate Edward Mills Purcell in 1963. Along with David Griffiths' Introduction to Electrodynamics, this book is one of the most widely adopted undergraduate textbooks in electromagnetism. A Sputnik-era project funded by the National Science Foundation grant, the book is influential for its use of relativity in the presentation of the subject at the undergraduate level. In 1999, it was noted by Norman Foster Ramsey Jr. that the book was widely adopted and has many foreign translations.The 1965 edition, now supposed to be freely available due to a condition of the federal grant, was originally published as a volume of the Berkeley Physics Course (see below for more on the legal situation.) The third edition, released in 2013, was written by David J. Morin for Cambridge University Press and included the adoption of SI units. Source: Wikipedia (en)
