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. For example, on page 96, "Equations 2.

The first is an integral over the charge distribution: 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. 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.

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. 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. It is just a simple equation that can be written in one line. Even if you are already familiar with special relativity, I recommend that you read the chapter carefully.

I don't think that you might have seen such kind of meticulous explanations about relativistic energy and momentum in other books as follows on page However, a closer inspection of Eqs. It is just conceivable, therefore, that a massless particle could carry energy and momentum, provided it always travels at the speed of light. Although Eqs. Personally, I would suggest this argument as a joke, were it not for the fact that at least one massless particle is known to exist in nature: Photons do travel at the speed of light, and they obey Eq.

The title of the first chapter of the book is Vector Analysis. After the first chapter, readers are bound to begin to study electrostatics, electric potentials, electric fields in matter, and many more. The mathematics of the book is also the author's style, less formal and intuitive. I think if the reader is a very logically rigorous person, he may feel uncomfortable with a few arguments. Among them, I want to comment on the point charge and Dirac delta function.
