Corrections to the Instructor's Solution Manual. (These corrections have been made.

For another instance, on page , it says, "Some people regard these the Maxwell's four equations having expression with D and H as the "true" Maxwell's equations, but please understand that they are in no way more "general" than Eq. There are a lot of examples and problems in the book.

I've read most of the examples, but I solved only a few problems that seem to be interesting. Maybe some of you don't need any pencil and paper to read the book although I desperately needed them. The author even jokes at some pages. For example, on page 98, it says, "The electric field inside a conductor is zero. Because if there were any field, those free charges would move, and it wouldn't be electrostatics the title of the chapter any more.

There are many results that are induced from long mathematical calculations. But since in many places the author explains their meaning before or after the calculation in an intuitive way, you may find no trouble even if you skip the whole mathematical steps. If you need the part later, you can come back to that part at anytime.

Just a glance of them would be enough for many readers, especially, like myself, who just want to know what electrodynamics is about.

The book is concrete, lucid and thorough in its explanation as well. For example, on page , it says, "As it turns out, H is more useful quantity than D. In the laboratory, you will frequently hear people talking about H more often even than B , but you will never hear anyone speak of D only E. The reason is this: To build an electromagnet you run a certain free current through a coil.

The current is the thing you read on the dial, and this determines H or at any rate, the line integral of H ; B depends on the specific materials you used and even, if iron is present, on the history of your magnet.

On the other hand, if you want to set up an electric field, you do not plaster a known free charge on the plates of a parallel plate capacitor; rather, you connect them to a battery of known voltage.

It's the potential difference you read on your dial, and that determines E or rather, the line integral of E ; D depends on the details of the dielectric you're using. It often asks fundamental questions in many places. For example, on page 96, "Equations 2.

The first is an integral over the charge distribution: the second is an integral over the field. For instance, in the case of spherical shell the charge is confined to the surface, whereas the electric field is everywhere outside its surface. Where is the energy, then? Is it stored in the field, as Eq. Firstly, I wished that I would really understand the principles of batteries.

## Griffiths Intro to Electrodynamics

For instance, how is it possible to sustain a constant voltage difference? I had to be content with the fact that it is not an easy subject. Actually, the author recommends reading an academic paper in case the readers want to know about the principles of batteries. Secondly, I wished to learn about gauge invariance in electrodynamics. The electric and magnetic fields they are physically real can be expressed using electric and magnetic potentials they are only mathematical objects not having any physical reality , respectively.

But the choice of electric and magnetic potentials need not be unique. Here we have a freedom to choose like when we choose an antiderivative of a given function. While different choice of gauge gives different formulae, each choice of them is more convenient than others in its proper situation.

For this, I am very satisfied with the book. Thirdly, I wished to understand the relationships between relativity and electrodynamics. They are known to have intimate relationships.

## CHEAT SHEET

In fact, the paper on special relativity by Einstein begins with some problems of electrodynamics. For this purpose, it went beyond my expectations. It was extremely helpful. The book introduces relativity in the final chapter. In the first section, it begins with a question on electromagnetic induction; when a moving coil passes above a static magnet, a current by the magnetic force Lorenz force flows in the coil.

On the other hand, when a moving magnet passes above a static coil, a current by an electric force Faraday's law flows in the coil.

## Table of Contents

In his paper on special relativity, Einstein asked. And from there, the book introduces the basics of special relativity; time dilation, length contraction, Lorentz transformations, four-vectors, relativistic energy and momentum, relativistic dynamics, tensors. After that, the book sheds new light on classical electrodynamics from the point of view of relativity. There, we learn that "we can calculate the magnetic force between a current-carrying wire and a moving charge without ever invoking the classical laws of magnetism only assuming classical laws of electrostatics and relativity.

In addition, we can understand how a point charge moving in uniform velocity can generate a magnetic field note that a moving charge itself is not a current.

In the last section, the book formulates the Maxwell's four equations using tensor notations. If you're interested in creating a cost-saving package for your students, contact your Pearson rep. He held post-doctoral positions at the University of Utah and the University of Massachusetts Amherst , and taught at Hampshire College, Mount Holyoke College, and Trinity College Hartford before joining the faculty at Reed College, where he has taught for over 30 years.

Although his PhD was in elementary particle theory, his recent research is in electrodynamics and quantum mechanics.

The book features a friendly, informal style. Focuses clearly on basic electromagnetic theory, providing a sound platform for future exploration of related applications such as AC circuits, antennas, transmission lines, plasmas, optics, etc.

Features a more extensive coverage of radiation theory than most texts at this level. New to This Edition. Edits to the entire text have clarified arguments and eliminated ambiguities. New problems and new worked examples appear throughout, while selected unsuccessful ones have been eliminated.

All figures have been reviewed for accuracy and updated where necessary. The new section fully explores the actual mechanism in cases where magnetic forces are actually working. Erroneous passages have been corrected. Citations of recent literature appear throughout for those who wish to pursue a particular topic in greater depth.

This literature helps reinforce the point that electrodynamics is a vibrant and dynamic field, even after years. Table of Contents 1. Vector Analysis 2. Electrostatics 3.In fact, the paper on special relativity by Einstein begins with some problems of electrodynamics.
