- Midterm-exam information. The exam is Thursday November 1 at the
usual class time.
The exam is open-book, meaning you are welcome to refer to Jackson
in "paper" or "electronic" form, no other reference materials are
to be used. The exam includes chapters 1 through 3.6 in Jackson.
All material, including lectures, homework, and text material may appear in the exam.
The exam has three problems: two have spherical geometries,
one has a 2D cylindrical geometry.
You will write your solutions directly on the exam.
You may bring scratch paper, but nothing on scratch paper will
be graded.
Here is a practice exam.

- Final-exam information. The exam is Wednesday December 12 at 4:30pm.
The exam is open-book, meaning you are welcome to refer to Jackson
in "paper" or "electronic" form, no other reference materials are
to be used. The exam includes chapters 1 through 5.8 in Jackson.
All material, including lectures, homework, and text material may appear in the exam.
You will write your solutions directly on the exam.
You may bring scratch paper, but nothing on scratch paper will
be graded.
Here is a practice exam.
The exam consists of four questions.
The first, the longest, is on vector potential.
The second is a calculation of fields in the gap of a magnet.
The third is a calculation of fields near a magnetized material.
The forth is a problem on magnetic forces and energies.
FAQs. Q: "Questions 3 and 4 on the practice exam ask about inductance, but I don’t think we have covered that yet in class. I just wanted to check whether inductance will be on the final." A: There won’t be inductance questions as such,
since we haven’t covered Faraday’s Law, where the inductance
concept is rooted.
But, e.g., the image current concept is fair game, not to say
there will be an image-current question.

Lecture Instructor's Comments
Welcome to Physics 513, the first of a three-quarter sequence of graduate
classical electrodynamics.
I hope you find this course challenging and stimulating.
The topic of electrodynamics is crucial for understanding the underpinnings of
the physical and biological sciences. It's also crucial for modern technology.
You will need a working knowledge of Jackson chapters 1-16 in order
to converse sensibly with your colleagues.
Regarding the course: We will use Jackson's text "Classical Electrodynamics".
You might want more details than found in Jackson, or perhaps you'd like
an alternative approach. In which case you might want to look at Panofsky and Phillips
"Classical Electricity and Magnetism". Two very good, very readable, books for some
slightly more formal aspects of the classical field theory are Landau and Lifshitz
"The Classical Theory of Fields" and "Electrodynamics of Continuous Media".
Another nice thing about Landau and Lifshitz
is halfway through "Theory of Fields" you're on to General Relativity rather seamlessly.
A slightly more elementary alternate text is Slater and Frank "Electromagnetism".
Most homework problems, and indeed the problems in most texts, are adapted from
Smythe "Static and Dynamic Electricity", a challenging text.
There is no perfect text, and every text has gems scattered throughout.
Mathematical methods are interspersed throughout the course as needed.
For a math refresher, you could refer to Dennery and Krzywicki "Mathematics for Physicists".
That said, this quarter we will follow Jackson's text somewhat closely.
Syllabus The syllabus for 513 starts with chapter 1 in Jackson.
We'll then follow the text in more or less the text ordering. We will supplement
Jackson's presentation with added material. See above for the readings and lectures. You should try to
read the relevant text and added material before class; this will take time but there's
a big payoff in your understanding.
Grading 40% of your grade is assigned to the midterm exam,
40% to the comprehensive final exam,
20% to the homework. It is very rare for me to assign a grade less
than 3.0, usually this flags a student not turning in credible
problem sets or missing exams.
Midterm and final exams: There will be one midterm exam and a
final exam.
Exams are to be your own work; you are not permitted to collaborate with any other person.
The Physics Department reserves the right to ask for valid identification from any student during examinations.
Note that there are no make-up exams or make-up homeworks. Students with outside professional, service, or career commitments
(i.e. military service, professional conference presentation, etc.) conflicting exactly with the exam dates must contact
the instructor early in the quarter to establish alternate procedures.
Students who miss an exam or homework due to illness should contact the instructor as soon as
you are able to discuss alternate procedures.
Except for debilitating illness, students who miss an exam or homework without making prior arrangements
with the lecture instructor will get a zero for that score.
Except for illness and circumstances noted above, a final grade of 0.0 may be assigned to any student who misses a midterm exam
and a final grade of 0.0 will be assigned to any student who misses the final exam.
Re-grades: If you believe that points on an exam or homework were incorrectly totaled or if there's a gross error in the grading,
you may submit an exam or homework for regrading. To do so, you must resubmit the exam or homework to the instructor no later than at the beginning of the lecture following the one
in which it was returned. You must write a brief note on a separate piece of paper explaining the possible error in the grading,
and staple this note to the front of the exam or homework pages when you submit them for re-grading.
Do not make *any* changes or marks on any pages of the exam or homework.
A request for a regrade may result in re-grading of the entire exam or homework. Therefore your total score may increase or decrease.
Homework: Lecture homework will generally be assigned and collected weekly. You'll usually turn in homework on the
due-day at the beginning of class.
You may also leave the homework in the instructor's mailbox in the Physics Department Main office by 10:45am on the due-day.
Late homework receives zero points. Note that
not all the homework problems will be graded.
If you start working on the homework the day before it's due, you will not finish on time.
The graders will look for neatness and logic of presentation, points will be deducted for
lack of either. Words help in explaining your solution. I strongly encourage you to work collaboratively, but your submitted work must
be your own.
The lecture instructor and graders will ignore re-grading requests that are not reported promptly.
Communication: For administrative issues, it's best to contact me via email.
But, for physics questions, please don't use email (unless they are of the "yes/no" variety).
Physics is best discussed at my office hours. You are welcome to come by outside my office hours,
but please don't be offended if I'm too busy to talk.
