Introduction to Electrodynamics by D. J. Griffiths

4th Edition (ISBN-13: 978-1108420419), Cambridge University Press, 2017. (You can find errata on the homepage of the author.)

There also exists as a "Pearson new international edition" in paper-back (ISBN-10: 1-292-02142-X, ISBN-13: 978-1-292-02142-3) which however is not recommended. This is a collection of the chapters in the book, two out of three of the appendices and the pages on the inside of the cover (vector derivatives etc). It contains essentially the same material although all cross-references between chapters have been removed as each chapter is presented on its own (meaning that all chapters are presented as chapter nr 1 and that the index is a bit different than the original one). This also affects some of the problems and in fact some of them have been deleted. I will point to these cases during the course. You can find a list of corrections to this paper-back edition here. (See also the homepage of the author.)

If you get your hands on a copy of the 3rd edition that will also work.



Entire schedule is available at Live@Lund.

Hand-in tasks

Each of the three or four hand-in tasks will be published via Canvas (L@L), and individual solutions are to be submitted as PDF via L@L, typically within six days, i.e, at the latest on the Thursday in the week after the exercise session, at 5 PM. The solutions should be written in a nice and easily readable manner, or typeset using a computer.

N.B. the bonus rules.


Exam rules: You can bring one A4-sheet of own notes. Notes on vector calculus and trigonometry will be provided. NO electronic equipment whatsoever will be allowed.

Written exam: See schedule
Registration is compulsory, via the Student Portal

Lecture notes

Lecture notes covering most of the lectures will be made available here.
For notes on the rest of the course please go to the Canvas homepage

Problem solving sessions

Problems covered in the exercise sessions will appear here (* = challenge).
  • March 29: 1.15, 1.18, 1.32, 1.33, 1.34, *1.58, *1.61. (If you want to practice derivatives then we also suggest: 1.4, 1.11b, 1.22ab, 1.26d, 1.27, 1.28)
  • Exercises

    There are lots of useful problems in the book by Griffiths. Note that there are two classes of problems:

    For the first kind of problems we suggest that you look at all of them and think about how you would solve them. Below you find a list with the problems that we think are most useful. Evidently there are very many problems so do not try to solve all of them. For the second kind of problems I have listed those that I find especially useful below.

    Old exams

    Nov 2018 (and solutions)

    May 2018 (and solutions)

    Oct 2017 (and solutions)

    May 2017 (and solutions)

    Collection of some mathematical formulas that are useful for electromagnetism (updated April 1, 2019). Will be handed out at exam.

    Formulas you can use without deriving them (unless asked to).
