16/12/19: I have updated the
Course Summary
to include the section of the course on radiation from accelerating charges and to include a few
notes on the exam.

**
21/12/19: Here is a `extra' example sheet.
These problems are intended to be relevant to helping you understand and practice using the core material of the lectures, as part of your revision for the
January exam.

Here is a `bonus' example sheet to provide some extra practice at solving problems.

Bonus Example Sheet ...... Solutions.I shall organize some OPTIONAL bonus Electrodynamics sessions throughout the term. They will occur on some Wednesdays at 12:00-13:00.

There will be a few extra-curricular lectures and some sessions will take the form of a small bonus `Examples Class', in which we'll work on a new problem that I'll bring along to the session. These sessions are also an opportunity for you to ask questions about lectures so far. I'm happy to adapt the format and frequency of these sessions to the requests/needs of the students that turn up!I currently foresee these being at the following days/locations:

2nd October: Bonus Revision Lecture: Solutions to Laplaces Equation (example in cartesian coordinates)

16th October: Question For Optional Examples Class 1 ...... Solutions.

6th November: Bonus Session 3 - The Lorenz Gauge Condidtion and Cosmic Ray Muons

20th November: Bonus Session 4 - The appearance of objects moving at close to the speed of light. The website containing the animations used in the lecture can be found at: https://www.spacetimetravel.org/bewegung/

4th December: Questions For Optional Examples Class 2 ...... Solutions. -->

Here is the complete Course Summary and Notes on the Exam ..... Please let me know if you find any typos or other mistakes!

A summary of useful formulae concerning vector calculus, coordinate systems, etc Example Sheet on Vector Calculus

Pictures of the electric and magnetic fields produced by a point charge moving with constant velocity

The syllabus for the course as given in the Blue Book

Material relating to past exams may be found on Blackboard. Please look at the "Course Summary" for some notes on exams before January 2019, which is the first year I taught the course.

Do you have any questions about the physics, the lecturs, or the example sheets? Do you have any feedback on the lectures or other aspects of the course? Did you find any mistakes anywhere? I'd be very interested to hear from you! Please come and find me in Room 6.22 (Schuster) or:
