Electromagnetics by John D. Kraus (PDF)

Description

This fourth edition of the classic electromagnetics text has been extensively revised to present balanced, thorough coverage of both static and dynamic electromagnetics for today’s courses in the subject. It explains both the basic theory and its application to practical designs and contains many computer programs for running on a personal computer. Many new topics are presented including heart dipole; superconductors; wave absorption, fiber optics and dielectric resonators.

⭐The 1953 edition is striking in that it explains in sufficient detail graphical (Yes, by hand) methods for plotting electrostatic, magnetostatic, and electric current fields both inside and outside of materials including an Appendix A-2 which summarizes the relevant subjects. To date, I have only seen these graphical methods described in two other books on the subject: the equally old book by Ernst Weber and Moon & Spencer’s dissident text. [Supposedly A.D. Moore was the master of graphical field mapping, you might also find excellent field maps in the four (3 vols electrostatique and 1 vol magnetostatique) books by Durand.] When this graphical field cell method is applied to the subject of transmission lines the quantities of inductance and capacitance per unit length become crystal clear. Truly Kraus’ ability to clearly explain the fundamental field concepts and how they translated directly to real engineering design parameters (albeit simple ones in this case) is quite superb.The determination of characteristic impedance using a d-c measurement (p.427) is a very practical application of the electromagnetic similitude which I found to be a very interesting alternative to buying expensive software/equipment to calculate/measure the quantity. I am especially impressed of the through yet simple figures and graphs that shows the thoughtfulness Kraus had when putting this excellent teaching tool together. In the age before the internet this book had it all. Most impressive is a figure showing the magnetic field quantities (B,M,H) along the center line at a gap in a permanently magnetized iron ring – a figure that always comes to mind with I see the defining interrelation between these quantities.Finally, Kraus does not shy away from using an appropriate amount of mathematics introducing vector calculus as needed in a most physical and intuitive fashion and culminating in solving boundary value problems of partial differential equations applied to .I understand from the preface of the 4th edition (the last within his lifetime) that the author removed the sections of graphical plotting from the later editions (furthermore he also mentions removing the sections on plasmas in the 2nd edition from the later editions).One might wonder why I purchased this copy of Kraus’ Electromagnetics book that was first published in 1953. It was the result of several interactions I have had with “experts” in the Applied (Numerical and Computational) Electromagnetics/dynamics field. No less than 3 persons with 30+ years experience doing numerical solutions of Maxwell’s equations who either 1) were taught from an edition of this text or 2) teach from an edition of this text (and those are just the individuals that I remembered to ask! ). An anecdote that one of these individuals shared with me about the author, Kraus who he knew while he was working on his PhD at Ohio State which I think speaks volumes about the author… Kraus was not only a excellent theoretician (see his book on Antennas), but loved to do electricity and magnetism experiments. Supposedly, he went through and recreated all of the experiments of Michael Faraday for fun in his basement at home. A student of history will know that Michael Faraday repeated all of the known experiments and captured all of the know electricity and magnetism (including some in electrochemistry and other aligned fields) up to his time. I think this is why Kraus has such a strong grasp of the subject, because he knew it independent of both the mathematics and the secondhandedness that many textbook writers have today.Plainly said, there is no better from which to learn the bread and butter of Engineering Electromagnetics. Highly recommended for self taught learners. Sitting at the feet of this master will not be an effort in vain. Such a pleasure to read!

⭐This book was designed for the undergrad and beginning graduate/ambitious senior undergrad (for the later chapters that deal with PDE’s). It’s very well-written and even explains mathematical concepts like divergence and curl in a very clear manner, providing good examples to illustrate what can be tough to understand material. It’s very detailed and mathematically rigorous. I wish that more EM texts/physics books were written this way, because it includes real-world examples for many of the concepts. I like how the chapters are sequentially arranged and also titled to make the concepts clearer. For example, Faraday’s law is in the chapter entitled “Time-changing Electric and Magnetic Fields”. This gives the student a better perspective on crucial concepts, rather than only a so-called “conditional statement” within the chapter as most other books are written.I recommend this to the student seeking a thorough book where the concepts are more completely derived, not just “hand-waved” seemingly out of thin air as most popular undergraduate physics and EM books seem to do these days. That can be frustrating and impede a student’s learning, and it seems that many modern textbook authors “dumb-down” their texts in a disrespectful manner to the average student’s intellect. This isn’t how Kraus wrote this book, so if you read it and do the problems be prepared to be challenged!…in a good way.

⭐I am 71 years old and studied from this book in the 1960s when going for my BS in electrical engineering. My son graduated with his BS in electrical engineering a few years ago and when we had discussions about electrostatics I would show him information in this book. His textbook skipped much of the information that can be found in this book. Eventually my son made the comment that he would like me to will him this textbook. I bought this book for my son so he would have a good source of technical information at his fingertips. He was ecstatic. Besides, I am hoping it will be many years before my WILL is read.

⭐Best textbook EVER on practical as well as theoretical electromagnetics. I wished I had this book when I studied electromagnetics at University of Illinois at Urbana-Champaign.

⭐This is a professional work with chapter divisions in a logical receivable order. Maxwell’s equationsare given importance, and coordinate systems are treated in detail for solving problems. Muchdetail is given to the electric field and its properties. The physics aspects are presented as well.

⭐Use it all the time as my primary reference. Lots of stuff in this little book.

⭐I love this book. It’s packed with information and valid to many branches of engineering and science. You won’t go wrong if you get it.

⭐The material covered is good basic physics, the examples, though, appear to not have been proof read. Some of the errors are probably just oversight, but there are too many of them. Some are clearly just wrong. This would have been a much better book for self study if a solutions manual were available, even if solutions to odd or even problems were available the value of the book would be much higher. I have read other books by Fleisch and they were very good. This one does not quite make that list.

⭐I have currently read chapter 1 and 5 and parts of chapter 2, 3 and 4 and I must say that it does an excellent job. It should be noted, that the web-site is no longer available, but the files can be found elsewhere on the web. Other remarks is that the end results to examples contains errors on more than one occasion, i.e. a factor of 10 wrong in either direction if you plug in the numbers from the example on your calculator, but the procedure of the examples is correct. Also the answers to some problems appear to be incorrect, at least I’ve experienced on some occasions, that calculating the answer in more than one way, still didn’t produce the expected answer. So, the perfect thing for this book, would be a 6th edition with adequate proof-reading and making the files officially available again and perhaps introduce a student’s manual. Albeit the above mentioned, I still feel that it is worth 5 stars, since it handles a topic, which is inherently difficult, in a very good way and also puts real-life applications into the picture. So on that account, it does a very solid job and in many aspects a very self-contained book. Should be found on all electronics engineers to be and electronics engineers bookshelf.

⭐Item is overall in good condition, really helpful diagrams and content is in a easy & accessible format. Which can only be a good thing if you’ve ever had to study Maxwell’s equations. The only reason it isn’t five stars, is simply down to the item arriving slightly damaged.

⭐What an incredible book, in my opinion it’s one of the best book on electromagnetics especially the unsolved questions are cherry on the cake. Slowly but effectively it will help you to develop your concepts, the figures and explanations are equally amazing.

⭐Excellent comprehensive book for EMT.Should have this book for reference as it speaks more of application.

⭐Not worthy. Doesn’t have any proofs
