(See Tentative Schedule at the bottom of the page)
- You can bring two sheets of notes to the exam. You can
write on both sides.
- Bring a blue book and a pen or pencil.
- I will also provide various formulas. These are
not read yet (check back in a few days?) but I anticipate
that will include a copy of the front and back cover of
Griffiths.

Course Description:
Electrodynamics, Maxwells equations,
conservation laws, electromagnetic waves, potentials and
fields for moving charges, radiation, special relativity.
Textbook:
Introduction to
Electrodynamics, Griffiths, 5th
edition. Same as 110A (amazon
link).
The 4th edition is also fine.
I will be (mostly?) assigning homework problems from
the book (5th edition).
I need to know if there are students with the 4th
edition, so that I can pick problems that are in both
the 4th and 5th edition.
Additional
Material
- Some extra notes on the October 10 lecture: here.
- Some extra notes on the October 22 lecture: here
- About polarization of reflected and transmitted waves: here.
- An alternate derivation of the Lienart-Wiechert potential:
here
- Derivation of the fields from a charge moving at constant
velocity ( Example 10.4 in Griffiths): here.
Homework:
Homeworks should be turned in via Gradescope.
Code: 6J6Y3X
Note: the number of interesting/good E&M problems that one
come up with is somewhat limited.
If you search hard enough on the web, you are likely to be
able to find solutions to many of the assigned problems (or
to very similar problems). Apparently, the latest
version of ChatGPT can actually solve hard, graduate level,
E&M problems (!).
My recommendation is that you try hard to do the problems
yourself, or with your study group.
If you do end up getting help from the internet or other
sources, make sure you understand the solution, do not
just copy it down. Maybe just take a hint to get started
and then finish things by yourself.
To be clear: I am not encouraging you to do this, but I
recognize reality, and I also think that there is some learning
value
in looking things up, but only after you have made a good
effort. Careful: do not overdo it! Remember that in
the end you
will need to solve exam problems all by yourself.
In any case: if you get help with your homework from any source
(internet, friends, study group...), make a note of
it with your solution. You will not be penalized in any
way, but honesty is always good.
14 September: the homework schedule
below is tentative. Will be updated as needed.

Exams and Grading:
There will be one midterm and one final.
The midterm will be on Thursday,
November 7 during normal class time.
The final will be Tuesday,
December 10, 4-7 pm.
The final grade for this class will be calculated from a curve
based on your scores on the Homework (15%), Midterm (35%),
Final (50%).
For an example on how I previously arrived at the letter
grades for a class, see this link.
If you miss the midterm for a good reason (eg: illness), your
letter grade will be calculated based on the homework and final
only.
If you miss the final you will be given an incomplete. You
will take the Physics 110B final the next time that the class is
being offered.
If, on the other hand, this is your last class that you need to
graduate, we'll figure something else o
