TL;DR Summary: Book: Neoclassical Theory of Electromagnetic Interactions - A Single Theory for Macroscopic and Microscopic Scales
I've found the book of Babin & Figotin:
Neoclassical Theory of Electromagnetic Interactions - A Single Theory for Macroscopic and Microscopic Scales.
I like their...
Summary:: There seems to be a mismatch, in the "Maxwell's" equations, between the number of equations and number of variables.
I was trying to play around with the equations for Electromagnetism and noticed something unusual. When expanded, there are 8 equations, 6 unknown variables, and 4...
Background: an ordinary wire supports an external radial electric field proportional to voltage, and an internal axial field equal to current times resistance per unit length. The present question is whether the internal axial field has an external counterpart. The original question that...
What was the problem between Maxwell's EM theory and the principle of relativity? Why went the theory against the principle?
I understand that the EM theory says that Light was a wave and ether is it's medium.
On the other hand the principle of relativity says that there is no state of...
I'm wondering if one can arrive at E=mc^2 using only the physics of the late 19th century, in the following way:
As light waves pass over an electrically charged particle, they push it in the direction of the wave motion, transferring both (kinetic) energy and momentum to the particle. Let's...
just below eqn 3.25, it is said:
At any given time, Ex is constant
for all values of x, but of course, this possibility cannot
therefore correspond to a traveling wave advancing in the
positive x-direction.
Why can't Ex be a constant?

"An infnitely long hollow cylinder of radius ##a## has surface charge density ##σ_a##.
It is surrounded by a coaxial hollow cylinder of radius ##b## with charge density ##σ_b##. The charge densities are such that the total confguration is electrically neutral. Using whatever...
Hello,
Am starting to read Electromagnetic Theory. Can you suggest some good textbooks on the topic that will help clear the concepts.
Thanks in advance
Homework Statement
Problem: Sea water has k = 80 in the low frequency limit. Yet its refractive index is around 1.34. Explain the discrepancy
Homework Equations
For a non magnetic dielectric medium, the absolute refractive index in the low frequency range, is given by : n = √k...
Is EM theory in curved spacetime the same as "unification"?
I am wanting to learn about classical EM theory in curved spacetime (just curious) and I found this old thread containing some references https://www.physicsforums.com/showthread.php?t=3950
Is simply talking about the EM field in...
Claim:
\nabla \cdot \frac{\hat{e}_r}{r^2}=4\pi\delta^3(\vec{x})
Anyone know of a proof of this? (or a reference which covers it?) We need to show that
\frac{1}{4\pi}\int_0^R{(\nabla \cdot \frac{\hat{e}_r}{r^2})f(r)dr=f(0).
The claimed identity can be seen in the solution for...
Studying EM Theory??
Hi All,
Is it possible to study Electromagnetic theory without knowing the concepts of classical mechanics. I have studied Newtonian mechanics but does not have any idea about Lagrange and Hamiltonian mechanics. I am concentrating on the below topics in...
Hello,
I need to purchase two books, for EM theory and Thermodynamics. I have briefly used couple of books years back and I can't seem to remember their titles or author. I slightly remember that the EM book was a blue color with a lots of information for first year - 4th year...
