Classical Electrodynamics (Physics) 2nd Edition by Hans Ohanian (PDF)

Description

The New Edition Of This Classic Work In Electrodynamics Has Been Completely Revised And Updated To Reflect Recent Developments In Experimental Data And Laser Technology. It Is Suitable As A Reference For Practicing Physicists And Engineers And It Provides A Basis For Further Study In Classical And Quantum Electrodynamics, Telecommunications, Radiation, Antennas, Astrophysics, Etc. The Book Can Be Used In Standard Courses In Electrodynamics, Electromagnetic Theory, And Lasers. Paying Close Attention To The Experimental Evidence As The Basis For The Theoretical Development, The Book’S First Five Chapters Follow The Traditional Introduction To Electricity: Vector Calculus, Electrostatic Field And Potential, Bvps, Dielectrics, And Electric Energy. Chapters 6 And 7 Provide An Overview Of The Physical Foundations Of Special Relativity And Of The Four-Dimensional Tensor Formalism. In Chapter 8, The Union Of Coulomb’S Law With The Laws Of Special Relativity Gives Issue To The Relativistic Form Of Maxwell’S Equations. The Book Concludes With Applications Of Maxwell’S Equations In Chapters 9 Through 16: Magnetostatics, Induction, Magnetic Materials, Electromagnetic Waves, Radiation, Waveguides, And Scattering And Diffraction. Numerous Examples And Exercises Are Included.

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐I think it’s very unfortunate that more authors of undergrad E&M texts don’t follow the approach here.Most texts, like Wangsness and Griffiths, introduce electrostatics, and then magnetism completely independent of electrostatics, then Maxwell’s equations, fields, and then special relativity at the very end as an afterthought.This approach makes sense if you’re teaching engineers or undergraduates who you’re not certain will become physicists, but it’s a very artificial construction that does a massive disservice to electromagnetism as a theory.Instead, Ohanian spends the first five chapters on a rather standard discussion (arguably even somewhat compressed) on electrostatics, and then immediately introduces special relativity and the four-vector potential, culminating in the electromagnetic field tensor, and then derives magnetism from the properties of that tensor under Lorentz transformations. He then spends the rest of the book treating magnetism and electrodynamics in this fully relativistic picture. It’s far more clear and natural than the standard approach and the author should be commended.

⭐I took E&M this last spring using this book and it truly is an amazing textbook. This book is really beefy in that it covers a lot of material, it was intended for two semesters of Electromagnetism. I am very fond of the formalism he decided to use. He chose to start with Coulomb’s law and from there derived most everything else in the book. Ohanian developed the magnetism as a direct cause of relativity and electricity, and derived the necessity of the Field Tensor and the vector potential. This book is pretty heavy in theory, but it also dives into many applications such as materials and a concise treatment of ferromagnet materials as well as electromagnetic waves in solids. This book manages cover E&M with great breadth and depth. I would recommend this book to any upper division physics undergraduate.

⭐Too many steps left out in his derivations for my tastes.

⭐The contend is okay but when it comes to exercises it pretty much have nothing to do with the materials talked in the chapter. not a good reference to study. Should buy some other text book.

⭐Best advanced undergrad E&M book out there. One of the few that uses relativity to derive magnetism and sticks with CGS units – the only others being Purcell and Schwartz, which are at a lower level. SI units are grotesque in E&M and the reason why Jackson 3/e is a massive disappointment compared to Jackson 2/e (and the only reason why I refer to my Jackson 2/e instead of Panofsky and Phillips). Ohanian’s text is one of those “if you were stranded on a desert island and could have only five books, which ones would you choose” books. This text blows Griffiths away.

⭐This book is written with a balance of mathematical sophistication and physical intuition, I like Ohanian’s treatment of vector analysis compared to griffiths, he even introduced tensors early on (which is a benefit to the reader because vector analysis looks cleaner and easier to write, proofs are also more natural with tensors). So far, his treatment is more intuitive because of the relativistic approach to electrodynamics (which is indeed the case), I don’t understand other people who prefers treatments with less sophistication, but still end up needing to learn them later on, so why not learn it now, besides this book is for upper undergrad, certainly it will be sophisticated, this is Physics. This can certainly be used to replace or supplement Griffiths, but to me this is the best undergrad electrodynamics book.

⭐This comment is based on the 1st edition that I bought in 1989 when I was a student. Even though I never taught E&M I am quite fond of this beautiful subject so far.Although the level of this book is lower than Jackson or Greiner, and it doesn’t cover all about E&M, I find this book very readable. The author explains things so clearly , e.g. the meaning of local field (in dielectric chapter), Earnshaw’s theorem (in electroststic chapter), magnetization (in magnetic materials chapter), etc. 4D permutation symbol is also mentioned in the exercise. The style of writing is stunning, Ohanian begins with electrostatics but later on he approaches the subject via relativity! The one I like most is the Omega&k transformation between 2 frames- the doppler shift formula as described in Greiner p.473.Despite that I don’t know about the 2nd edition of this book but I guess the style of writing hasn’t chaged so much. For sure, the 1st.edn. is very well-written. It gives the reader clarity and insight into E&M. Apart from not covering everything like Lorrain&Corson, this book has its own identity and charm. I never regret of buying it, and I am happy every time of picking it up from the shelf. I think we have to admit a fact that, for any subject, we seem never fully satisfied for only one textbook. E&M is a subject in physics that needs a few (or more)books to strengthen our knowledges. If you have read other E&M books, try this one. You’ll most probably love it.

⭐Probably meant as a replacement for or an improvement on John David Jackson’s book of the same name. Alas, this book is an essentially inside-the-box take on the same material as Jackson’s. This author appears to have created an exhaustive set of references, but he failed to reference Heaviside’s Electromagnetic Theory or credit any of Heavyside’s more obvious contributions, i.e. the symbols.
