This is the second semester of a two-semester sequence in electrodynamics. In the first semester of Electromagnetism, we laid the mathematical foundations in electrodynamics and developed the physics of static electric and magnetic fields. In the course, we will cover the dynamics of electrical and magnetic fields, a much deeper and richer subject. You should continue to develop fluency in the requisite mathematical techniques and an understanding of the physical nature of the sources and nature of electric and magnetic fields. While this course requires a substantial amount of quantitative computation, I hope to be able to emphasize the physical (as opposed to the mathematical) nature of the EM fields. It is important not to loose sight of the physics when doing math!


Electromagnetism I (PHY 3223) or permission of the instructor. Students who take this course should have completed courses in differential equations (MAP 2302 or equivalent) and vector calculus (MAC2313 or equivalent).


Your success in this course is directly proportional to the amount of time you spend on solving the homework problems outside of class, be it on your own or with a group of other students. Problem sets are due in class on the due date. Homework will be graded on a 10 point scale and will count for 30% of your total grade. It is very important that you attempt to do all the problems; partial credit is one of the keys to success in this course.

Late Homework - Homework turned in after the due date will be graded down accordingly: a loss of 3 points for the first day and a loss of 2 points for each additional week.

There will be 7 homework assignments. Their schedule and selections are posted via Canvas. Their due dates will be indicated and strictly enforced. Constructive collaboration is encouraged, but you are required to write up your own final solution, and you must list the names of any and all collaborators and/or solution sources.


Exams: There will be a 2-hour midterm exam and a final exam. The midterm exam will count 30% and final 40% toward your final course grade.

Grades: Letter grades will be assigned on the basis of the overall course score out of 100. Your grad will be calculated as follows: 95 A+, 90 A, 85 A-, 80 B+, 75 B, 70 B-, 65 C+, 60 C, 55 C-, 50 D, 45 D-. Below 45: F.
