Are you want to strengthen your Electrodynamics portion for exams like IIT JAM, JEST, TIFR, etc? Then you must go with the Introduction to Electrodynamics PDF by Griffiths. Here, in this post, you will be able to download the book in PDF format for Free.

## Outlines of Griffiths Introduction to Electrodynamics PDF

This is a textbook on electricity and magnetism, designed for an undergraduate course at the junior or senior level. It can be covered comfortably in two semesters, maybe even with room to spare for special topics (AC circuits, numerical methods, plasma physics, transmission lines, antenna theory, etc.)

A one-semester course could reasonably stop after Chapter 7. Unlike quantum mechanics or thermal physics (for example), there is a fairly general consensus with respect to the teaching of electrodynamics; the subjects to be included, and even their order of presentation, are not particularly controversial, and textbooks differ mainly in style and tone.

## Changes in the Latest Edition of Griffiths Introduction to Electrodynamics

For the third edition, they have made a large number of small changes, in the interests of clarity and grace. He has also modified some notation to avoid inconsistencies or ambiguities. Thus the Cartesian unit vectors î, ſ, and Â have been replaced with Ê, and î, so that all vectors are bold, and all unit vectors inherit the letter of the corresponding coordinate. (This also frees up k to be the propagation vector for electromagnetic waves.) It has always bothered me to use the same letter r for the spherical coordinate (distance from the origin) and the cylindrical coordinate (distance from the z-axis).

A common alternative for the latter is p, but that has more important business in electrodynamics, and after an exhaustive search he settled on the underemployed letter s; Some readers have urged me to abandon the script letter r (the vector from a source point r’ to the field point r) in favor of the more explicit r – r’. But this makes many equations distractingly cumbersome, especially when the unit vector î is involved. He knows from his own teaching experience that unwary students are tempted to read z as r—it certainly makes the integrals easier!

He has inserted a section in Chapter 1 explaining this notation, and He hopes that will help. If you are a student, please take note: r=r-r’, which is not the same as r. If you’re a teacher, please warn your students to pay close attention to the meaning of n. He thinks it’s a good notation, but it does have to be handled with care.

The main structural change is that he has removed the conservation laws and potentials from Chapter 7, creating two new short chapters (8 and 10). This should more smoothly accommodate one-semester courses, and it gives a tighter focus to Chapter 7. He has added some problems and examples and removed a few that were not effective). And he has included more references to the accessible literature (particularly the American Journal of Physics).

He realizes, of course, that most readers will not have the time or inclination to consult these resources, but he thinks it is worthwhile anyway if only to emphasize that electrodynamics, notwithstanding its venerable age, is very much alive, and intriguing new discoveries are being made all the time. He hopes that occasionally a problem will pique your curiosity, and you will be inspired to look up the reference–some of them are real gems.

As in the previous editions, he distinguishes two kinds of problems. Some have a specific pedagogical purpose, and should be worked on immediately after reading the section to which they pertain; these he has placed at the pertinent point within the chapter. (In a few cases the solution to a problem is used later in the text; these are indicated by a bullet (.) in the left margin.) Longer problems, or those of a more general nature, will be found at the end of each chapter.
