Electricity and Magnetism is a standard textbook in electromagnetism originally written by Nobel laureate Edward Mills Purcell in 1963. [1] Along with David Griffiths' Introduction to Electrodynamics , this book is one of the most widely adopted undergraduate textbooks in electromagnetism. [2] 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. [3] In 1999, it was noted by Norman Foster Ramsey Jr. that the book was widely adopted and has many foreign translations. [4]
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 status). The third edition, released in 2013, was written by David J. Morin for Cambridge University Press and included the adoption of SI units.
The Berkeley Series was influenced by MIT's Physical Science Study Committee that was formed shortly before Sputnik was launched in 1956. The satellite could be seen from rooftops at MIT with times published in the local Boston newspapers. [3] The space race caused a shake-up in the US scientific establishment and it led to new approaches to science education in the US. [3]
In 1966, Benjamin F. Bayman reviewed the first edition. [5] Bayman both commended and criticized the book. He questioned whether the book is appropriate for college sophomores to read, and commended the book, calling it as a "beautiful book on electricity and magnetism". [5] Bayman highlights the chapters that deal with magnetic and electric fields in matter.
According to a 1998 review of the second edition, [6] the first edition "has not aged" and was "the best introductory textbook I have seen". The reviewer points out that the Berkeley Physics Series limitations and the book's dearth of references to wave phenomena are its two biggest issues. The review states that the "results are spectacular" and that problems were resolved in the latest edition. [6]
The main criticism of the book, according to a 2012 review of a second edition, is that it doesn't provide answers for the problems that are presented at the conclusion of each chapter. [7] The reviewer notes that the lack of many calculation examples in the text made this issue worse. [7] Another issue raised was the book's usage of cgs units rather than SI units. [7] The review continues, stating that "despite the criticism, this text is very beautifully written and gives a well-structured and clear insight into the topic" and "can be recommended to any student" for use in an introductory course on electromagnetic.
Norman Foster Ramsey Jr. called it a "excellent introductory textbook" in his 1999 obituary for Purcell. [4] Roy Schwitters writes in a Physics Today review of Andrew Zangwill's Electrodynamics that he advises undergraduates to pick up the third edition of this book. Jermey N. A. Mathews listed it as one of the five books that stood out in Physics Today in 2013, acknowledging that there were issues with the previous writings, however, the publication noted that "clearly, Purcell's E&M matures slowly." [8]
In 2013, Michael Belsley [9] noted that the third edition of the textbook was a significant improvement, especially appreciating its treatment of magnetism as a relativistic phenomenon. [9] In 2013, Conquering the Physics GRE described the third edition as an elegant introduction that emphasizes physical concepts over mathematical formalism. [10] In 2013, Sam Nolan praised it as an excellent updated introduction to the classic 50-year-old text. Another review referred to the third edition as a welcome update to the original work. [11] Another review referred to the third edition as a welcome update to the original work. [3]
Because it was funded by the National Science Foundation, the original editions of the Berkeley Physics Series contained notices on their copyright pages stating that the books were to be available royalty-free in five years. The copyright page [12] of the original 1965 edition of Electricity and Magnetism includes a notice stating that it is available for use by authors and publishers on a royalty-free basis after 1970. The authors got lump-sum payments but did not receive royalties. [13] The copyright page of the 1965 edition says to obtain a royalty-free license from Education Development Center. [12]

Benjamin Crowell, [20] [21] [22] a retired [23] Fullerton College physics teacher, wrote that Cambridge University Press refused to provide him the contact information for the copyright owner, but instead forwarded the request to the copyright owner. Crowell wrote that this made it effectively impossible to obtain the royalty-free license promised under the original government contract and that this uncertainty places an open-source version of the first edition in legal limbo.

In physics, electromagnetism is an interaction that occurs between particles with electric charge via electromagnetic fields. The electromagnetic force is one of the four fundamental forces of nature. It is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics and magnetism, which are distinct but closely intertwined phenomena. Electromagnetic forces occur between any two charged particles. Electric forces cause an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs between charged particles in relative motion. These two forces are described in terms of electromagnetic fields. Macroscopic charged objects are described in terms of Coulomb's law for electricity and Ampère's force law for magnetism; the Lorentz force describes microscopic charged particles.
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.
An electromagnetic field is a physical field, mathematical functions of position and time, representing the influences on and due to electric charges. The field at any point in space and time can be regarded as a combination of an electric field and a magnetic field. Because of the interrelationship between the fields, a disturbance in the electric field can create a disturbance in the magnetic field which in turn affects the electric field, leading to an oscillation that propagates through space, known as an electromagnetic wave.
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.
A magnetic field is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, electric currents, and electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function assigning a vector to each point of space, called a vector field.
An electric field is the physical field that surrounds electrically charged particles. Charged particles exert attractive forces on each other when their charges are opposite, and repulse each other when their charges are the same. Because these forces are exerted mutually, two charges must be present for the forces to take place. The electric field of a single charge describes their capacity to exert such forces on another charged object. These forces are described by Coulomb's law, which says that the greater the magnitude of the charges, the greater the force, and the greater the distance between them, the weaker the force. Thus, we may informally say that the greater the charge of an object, the stronger its electric field. Similarly, an electric field is stronger nearer charged objects and weaker further away. Electric fields originate from electric charges and time-varying electric currents. Electric fields and magnetic fields are both manifestations of the electromagnetic field, Electromagnetism is one of the four fundamental interactions of nature.
In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface. It is usually denoted Φ or ΦB. The SI unit of magnetic flux is the weber, and the CGS unit is the maxwell. Magnetic flux is usually measured with a fluxmeter, which contains measuring coils, and it calculates the magnetic flux from the change of voltage on the coils.
Edward Mills Purcell was an American physicist who shared the 1952 Nobel Prize for Physics for his independent discovery of nuclear magnetic resonance in liquids and in solids. Nuclear magnetic resonance (NMR) has become widely used to study the molecular structure of pure materials and the composition of mixtures. Friends and colleagues knew him as Ed Purcell.
A Treatise on Electricity and Magnetism is a two-volume treatise on electromagnetism written by James Clerk Maxwell in 1873. Maxwell was revising the Treatise for a second edition when he died in 1879. The revision was completed by William Davidson Niven for publication in 1881. A third edition was prepared by J. J. Thomson for publication in 1892.
In electromagnetism, electric flux is the measure of the electric field through a given surface, although an electric field in itself cannot flow.
John David Jackson was a Canadian–American theoretical physicist. He was a professor at the University of California, Berkeley and a faculty senior scientist emeritus at Lawrence Berkeley National Laboratory.
Relativistic electromagnetism is a physical phenomenon explained in electromagnetic field theory due to Coulomb's law and Lorentz transformations.
Heaviside–Lorentz units constitute a system of units and quantities that extends the CGS with a particular set of equations that defines electromagnetic quantities, named for Oliver Heaviside and Hendrik Antoon Lorentz. They share with the CGS-Gaussian system that the electric constant ε0 and magnetic constant µ0 do not appear in the defining equations for electromagnetism, having been incorporated implicitly into the electromagnetic quantities. Heaviside–Lorentz units may be thought of as normalizing ε0 = 1 and µ0 = 1, while at the same time revising Maxwell's equations to use the speed of light c instead.
The Berkeley Physics Course is a series of college-level physics textbooks written mostly by UC Berkeley professors.
This article is a progressive and labeled list of the SI electric charge orders of magnitude, with certain examples appended to some list objects.
The Feynman Lectures on Physics is a physics textbook based on a great number of lectures by Richard Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". The lectures were presented before undergraduate students at the California Institute of Technology (Caltech), during 1961–1963. The book's co-authors are Feynman, Robert B. Leighton, and Matthew Sands.
Galilean electromagnetism is a formal electromagnetic field theory that is consistent with Galilean invariance. Galilean electromagnetism is useful for describing the electric and magnetic fields in the vicinity of charged bodies moving at non-relativistic speeds relative to the frame of reference. The resulting mathematical equations are simpler than the fully relativistic forms because certain coupling terms are neglected.
Classical Electrodynamics is a textbook written by theoretical particle and nuclear physicist John David Jackson. The book originated as lecture notes that Jackson prepared for teaching graduate-level electromagnetism first at McGill University and then at the University of Illinois at Urbana-Champaign. Intended for graduate students, and often known as Jackson for short, it has been a standard reference on its subject since its first publication in 1962.
Electromagnetism is one of the fundamental forces of nature. Early on, electricity and magnetism were studied separately and regarded as separate phenomena. Hans Christian Ørsted discovered that the two were related – electric currents give rise to magnetism. Michael Faraday discovered the converse, that magnetism could induce electric currents, and James Clerk Maxwell put the whole thing together in a unified theory of electromagnetism. Maxwell's equations further indicated that electromagnetic waves existed, and the experiments of Heinrich Hertz confirmed this, making radio possible. Maxwell also postulated, correctly, that light was a form of electromagnetic wave, thus making all of optics a branch of electromagnetism. Radio waves differ from light only in that the wavelength of the former is much longer than the latter. Albert Einstein showed that the magnetic field arises through the relativistic motion of the electric field and thus magnetism is merely a side effect of electricity. The modern theoretical treatment of electromagnetism is as a quantum field in quantum electrodynamics.
So I contacted Ed Purcell's sons, Dennis and Frank, and also Cambridge University Press, and everyone was on board.
