Introduction to Electrodynamics is a textbook by physicist David J. Griffiths. Generally regarded as a standard undergraduate text on the subject, [ 1 ] it began as lecture notes that have been perfected over time. [ 2 ]
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]
For undergraduates, there are several widely used textbooks, including David Griffiths' Introduction to Electrodynamics and Electricity and Magnetism by Edward Purcell and David Morin. [5] Also at an undergraduate level, Richard Feynman's classic Lectures on Physics is available online to read for free. [6]
It is followed by accessible treatments of quantum electrodynamics, the strong and weak interactions, and gauge theories." [ 3 ] The Times Higher Education review said, "The first edition of this textbook was notable for providing a clear and logical overview of particle physics that was at the right level for advanced undergraduates...
Griffiths is principally known as the author of three highly regarded textbooks for undergraduate physics students: Introduction to Elementary Particles (published in 1987, second edition published 2008), Introduction to Quantum Mechanics (published in 1995, third edition published 2018), and Introduction to Electrodynamics (published in 1981 ...
Position vectors r and r′ used in the calculation. The starting point is Maxwell's equations in the potential formulation using the Lorenz gauge: =, = where φ(r, t) is the electric potential and A(r, t) is the magnetic vector potential, for an arbitrary source of charge density ρ(r, t) and current density J(r, t), and is the D'Alembert operator.

More than two dozen House Republicans are asking President-elect Donald Trump to terminate the Internal Revenue Service's (IRS) free direct tax filing system as soon as day one of his presidency.
Since the potentials are only defined up to gauge equivalence, we are free to impose additional equations on the potentials, as long as for every pair of potentials there is a gauge equivalent pair that satisfies the additional equations (i.e. if the gauge fixing equations define a slice to the gauge action). The gauge-fixed potentials still ...
