TL;DR Summary: How much special relativity Is needed for Edward M. Purcell & David J. Morin It clearly is needed to fully understand this book and I have what seems like a good book that introduces relativity (A.P. French) But I am not wanting to start it yet and it’s around 300 pages long...

Hi I am coming up to the end of first year electromagnetism using the book University Physics. I will be honest there’s a lot of information crammed into a few hundred pages and it was my first ever exposure to EM. I never did it in school. I feel like its give me a good overview but i don't...

Is there a freshman dedicated EM book other than Purcell? I am not interested in the standard combo texts or Feynman.

The author start of with $\frac{1}{(y+\sqrt{3})^2} - 2 \cdot \frac{1}{1 + y^2} \left( \frac{y}{\sqrt{1+y^2}} \right) = 0$ and arrives at the equation $y = \frac{(1+y^2)^{3/2}}{2(y+\sqrt{3})^2}$ The solution is merely by iterating (use an initial guess value of y, calculate the RHS, then use this...

Hello, I've been researching textbooks to use for my first-year E&M course and since I have no previous knowledge of E&M, I've been reading University Physics by Young et al. and Serway's book. I am pretty annoyed at the verbosity of the texts and the banal exercises where most exercises are...

Dear all, I am looking for an introductory QED textbook (or quantum optics if not) that also covers QED cavity and Purcell effect in one of its chapters. I am not planning to extensively understand every single detail about QED cavity and Purcell effect since I am not a physicist and I don't...

I have already taken the following online courses: - Physics 1 (calc based, mechanics) - Linear Algebra - Calculus 1 - Calculus 2 - Electronics technician by trade Next semester I will be taking multi variable calculus, in preparation for a brick and mortar Canadian university for fall of 2018...

Hi, I've 2 em texts: Purcell, ( Electricity&magnetism ) and the Griffiths (intro to electrod.) On which of the two, is best to study ?

In Berkeley Physics Course (Volume II) on Electricity and Magnetism: https://www.scribd.com/doc/128728926/Electricity-and-Magnetism-Berkeley-Physics-Course-Purcell ...Purcell discusses the invariance of charge (Section 5.4), the electric field measured in different frames of reference (Section...

Hi, I was reading Purcell's Electricity and Magnetism. It says that if there were a magnetic charge, its field would behave like an electric charge (field pointing out radially and magnitude decreasing as 1/r^2). Why? Could this be deduced from magnetic fields produced by electric charges? If...

I heard that Griffith's Electrodynamics is at a similar level of Purcell's book on electricity; is it fine if someone goes into a graduate level electrodynamics book right after Purcell?

Hi everyone, I have a question (or three) regarding Purcell's discussion of image charges, in pg 137-139 of the third edition of his EM book. He goes over the classic image charge example: a plane held at zero potential, and a charge Q a distance h above it. I'm fine with everything he...

How does KIP: Fundamentals of Electricity and Magnetism compare against Purcell? Are they at the same level? Or would focusing on Purcell be a better option? I took an honors EM class and are assigned text was Purcell. It was the first time our school used Purcell for an honors sequence...

In chapter 5 of Purcell's Electricity and Magnetism, he shows using principles of special relatives that the magnetic force of a current carrying wire on a moving charge is equivalent to the charge experiencing an electric force in its own frame of reference. His argument is that when the...

Since the advent of relativity in 1905, physicists have understood electromagnetism as the first example of a unified field theory. However, the relativistic insight is often ignored in freshman physics classes, so that students learn the subject as it was understood in the 19th century. An...

1. The question: This question is from purcell's E&M book (3.71). (a) The plates of a capacitor have are A and separation s (assumed to be small). The plates are isolated, so the charges on them remain constant, the charge densities are +-σ. A neutral conducting slab with the same area A but...

These are more mathematics than they are problems with understanding of physics. 1. Homework Statement The problems are 2.18 and 2.12 which are as follows, 2.18A hollow circular cylinder, of radius a, and length b, with open ends, has a total charge Q uniformly distributed over its surface...

I know that Kleppner and Purcell are deeper, but does HRK even come close? Also how far is HRK from HRW in depth of coverage and difficulty? Thanks!

What would be a good mechanics book after K&K that includes Lagrangian and Hamiltonian mechanics? Also, would Griffiths' Electrodynamics be suitable after Purcell? What about Griffiths' Quantum Mechanics (ignoring the math pre-reqs)?

Homework Statement The question is 1.3 from Purcell E&M 3rd edition. It is asking you what the force on a point charge q is at the tip of a hollow cone (no bottom surface). Homework Equations F = (1/4pie0)*(qQ / r^2) The Attempt at a Solution I have worked on this on and off...

Thirty years after learning E&M from the wonderful book by Purcell, I noticed that the copyright page of my dog-eared copy of the 1965 edition includes a notice stating that it is available for use by authors and publishers on a royalty-free basis after 1970. The book has gone through two more...

So I have been interested in trying to do some physics that require more heavy use of calculus. I plan on getting Kleppner's mechanics book as well as Purcells E&M book. Having been out of school for so long, I need to brush up on my calculus, and I was wondering what the best approach would...

should i do Purcell or go straight to griffiths if the math is no problem and i want the one that provides a better conceptual understanding?

Homework Statement Imagine that all the molecular dipoles in a cup of water could be made to point down. Calculate the magnitude of the resulting surface charge density at the upper surface of the water, and express it in electrons per square centimeter. Homework Equations The...

Homework Statement This is to look at the effect of damping on the frequency of a series RLC circuit. Let W=1/(sqrt(LC)) be the frequency of an undamped circuit. Suppose enough resistance is added to bring Q down from infinity to 1000. By what percentage is the frequency, ω, thereby shifted...

Homework Statement There is a picture of two possible set ups for a dynamo-- the only difference I can see is the direction in which the main shaft rotates. He says that it is a "self-excited dc generator" because the rotation of the shaft inside of the single loop coil provides the changing...

Homework Statement A wire lies at height z=h carrying current parallel to the y-axis. A square loop, of side length b, is moving in the direction of +x with a velocity v. Find the magnitude of the emf at the moment when the center of the loop crosses the y-axis. Homework Equations...

"Flux in Through/ Out of Caps" Purcell Homework Statement I'm working problem 5.11 in Purcell's E&M book. It's about relativistic particles, and the eventual condition about angles at which the E-field lines are directed. The ultimate goal is to prove that tan(\varphi)=\gammatan(\theta)...

"Qausi-static" displacement current (Purcell) Hello all, On page 329, chapter 9 of Purcell's E&M book, he describes why the "displacement current" produces nearly zero magnetic field for slowly varying fields. By taking the curl of the displacement current Jd, he shows that...

So I'll be taking undegrad E&M 1 next semester and was looking for a good book to prepare for it before the semester starts. People seem to like Griffiths and Purcell generally. Shwartz also seems to have some good reviews (and is quite cheap) on Amazon but I'm not quite sure what level it is...

Does anyone know where I can purchase the hardcover 1985 Electricity and Magnetism? Some schools, such as Caltech and MIT, still use the book; however, Caltech does not have it in their online bookstore and MIT lists an 09 edition (which I assume is an ebook?). Some copies are floating...

Hey guys, I used Kleppner and Kolenkow last semster,it is an alright book, although sometimes a bit to dry and heavy in its explanations, and am using Purcell now, the Berkeley edition, very happy and satisfied by it. Just curious if there are any fellow physics students using these books...

A spherical volume of radius, a, is filled with charge of uniform density, p. We want to know the potential energy, U, of this sphere of charge, that is, the work done in assembling it. Calculate it by building the sphere up layer by layer, making use of the fact that the field outside a...
