Reddit reviews Electricity and Magnetism

The two "classic" intro physics texts are Kleppner and Kolenkow for mechanics and Purcell for E/M. These are pretty standard for honors intro physics classes across the US.

Both are good books which are considerably more theoretical and rigorous than the typical "Physics for Scientists and Engineers" that I'm guessing you're using (and will not leave results like the ones you give unjustified, for example).

Nevertheless, I don't think you're going to find many physics textbooks written with the strict, precise logic of a proper math book (at the undergraduate level, at least). Physicists are simply interested in different things than mathematicians.

Also, remember that physics is a science, and it is informed by both logical deductions AND experiments.

electricity and magnetism by purcell and morin

edit: as a counter to the griffiths suggestion, i have read good things about modern electrodynamics by zangwill, but i have no personal experience with the book.

Take a charge just sitting there, and suddenly whack it. A moving charge has a different electric field than a stationary one, it's strongest in the plane perpendicular to the motion. The field lines for this moving charge will be straight, but squished towards that plane.

But if you're a light year away, you can't know that instantly. You'll still see the same field that the stationary charge made. The information that the charge is now moving propagates out at the speed of light, so you get a shell moving outward in which the field suddenly shifts, from the stationary charge field to the moving charge field. That is a light wave.

You can also see from this description how the intensity depends on what angle you're at, and why it depends on acceleration (the faster you accelerate, the thinner the shell/wave and the bigger the change in E, so the big E in the shell is even bigger).

Why do you need acceleration? If the charge has been uniformly moving forever, the field will be "correct" everywhere. Of course, if you suddenly stop it, you'll launch another wave. If you move the charge sinusoidally, you'd get pretty much what you'd expect.

I can't draw a nice picture, but this is basically what's on the cover of the latest edition of Morin/Purcell E&M. That book is where I heard about this nice intuitive picture, which is great for people like me who can't do advanced math. :D

If I were you, I would study from Purcell (Berkeley physics course volume number 2). https://www.amazon.com/Electricity-Magnetism-Edward-M-Purcell/dp/1107014026 This is the best to begin with. And DO all the problems! After that if you still want better understanding, Griffiths - Introduction to electrodynamics is very good. Do not touch Feynman or Landau until you complete those 2, they are very bad for beginers but after you are familiar with the subject they are true gems.

For freshman/ sophmore honors EM in the US, I think that's A-level in Britain or something? Anyways, Purcell and Morin's Electricity and Magnetism is absolutely great.

Basically it was written by Purcell, Nobel Prize winner in 1952, and uses special relativity and a few other assumptions to derive all of electricity and magnetism, rather than the other way around. Morin came along in the third edition, added a bunch of problems and changed the units from Gaussian to MKS. If your mechanics course covers some special relativity, I strongly recommend this book.

Warning, vector calculus is necessary, Purcell gives an overview, but it's not a full treatment.

maybe? or griffiths

If you are looking for a E & M textbook, I would absolutely recommend Electricity and Magnetism by Purcell (https://www.amazon.com/Electricity-Magnetism-Edward-M-Purcell/dp/1107014026/ref=sr_1_1?ie=UTF8&qid=1517530006&sr=8-1&keywords=electricity+and+magnetism).

You're English is great.

I'd like to reemphasize /u/Plaetean's great suggestion of learning the math. That's so important and will make your later career much easier. Khan Academy seems to go all through differential equations. All of the more advanced topics they have differential and integral calculus of the single variable, multivariable calculus, ordinary differential equations, and linear algebra are very useful in physics.

As to textbooks that cover that material I've heard Div, Grad, Curl for multivariable/vector calculus is good, as is Strang for linear algebra. Purcell an introductory E&M text also has an excellent discussion of the curl.

As for introductory physics I love Purcell's E&M. I'd recommend the third edition to you as although it uses SI units, which personally I dislike, it has far more problems than the second, and crucially has many solutions to them included, which makes it much better for self study. As for Mechanics there are a million possible textbooks, and online sources. I'll let someone else recommend that.

Purcell's book on E&M starts with relativity and derives magnetism as a relativistic effect.

Now that the 3rd edition has been published, used copies of the 2nd edition of The Art of Electronics is super cheap. I think this is the best intro circuits book for self study. Alternatively, I've really enjoyed Practical Electronics for Inventors too, and it covers more modern stuff (like it has a chapter on arduino). Both of these start with the basics, though Practical Electronics written for a more general audience so it is easier on the math.

For electromagnetics, I've heard Electricity and Magnetism is pretty good. It does cover some circuits stuff, but so much of circuits is about electronic components that you really need a dedicated circuits book to understand them.
