Description of the class


This class correspond to the second part of a two-semester sequence of classes intended to cover the standard topics of classical electrodynamics in a mathematically sophisticated and conceptually rigorous manner. This second part will be centered on the description of time dependent electromagnetic fields and their interactions with charges and currents.


Lectures

Tuesday and Thursday, 11:00-12:30, P&A Room 184.

Textbook

Textbook for the class
Introduction to Electrodynamics (4th Edition) by D. Griffiths. The course will cover Chapters 7-12.

Additional resources
Berkley Physics Course on "Electricity and Magnetism" by E. Purcell and D. Morin.
Lectures on physics - vol II by R. P Feynman.
Foundations of Electromagnetic Theory by J. R. Reitz, F. J. Mildford and R. W. Christy.

Office hours

Instructor
Tuesdays and Thursdays 12:30-2:00 in Room 1136. These are nominal office hours, you are welcome to come into my office at other times too if your questions cannot wait, although I would appreciate if you could send an email announcing your visit. Sometimes, this drop-in approach may not work if I am very busy or your question requires more than just a few minutes, but in that case I will ask you to come back at a later time.

Teaching assistant
The teaching assistant is Nazanin Mosavian (nmosavian@unm.edu). She will be available on Thursdays from 1.00 pm to 2.00 pm in P&A lobby for you to discuss any homework grading issues you may have (please send her an email to arrange an appoinment).

Grading

The grading in the course will be based on your performance in homework assignments, two midterm exams, and a final exam. The contribution to the final grade is as follows:

  1. Homework: the best (n-1) scores of the n assignments will represent the 20% of the final grade.
  2. Midterm exams: each of them will represent the 25% of the final grade.
  3. Final: will represent the remaining 30% of the final grade.

The MT exams are tentatively scheduled for September 27 and November 3, during (extended) class time, and the final exam will be held on December 13.

Homework assignments

There will be 9 assignments during the semester each with 4-6 problems apiece. The assignments will be given throughout the semester and will be posted in the tentative schedule about 7-10 before they are due. Late homework policy: homework returned in the next 3 days after the due dat will be accepted but 50% penalization. After 3 days of the due date the corresponding solutions will be posted here.

Problems class

Listed officially as Phyc 416.001 (Thursdays: 2:00 - 3.00 pm, Room 184).  This is a very important adjunct to the main lecture class. It will provide you additional practice with solving problems beyond the homework assignments and self study. We will also cover some examples of numerical approaches to solve problems in electrodynamics. Furthermore, the class will also give you a valuable opportunity to bring to my attention your difficulties with any concepts covered in the lecture class so I can address them in a group setting. The problem sheets would be posted here the Friday before the problem class. The corresponding solutions will be posted after the class. You will receive credit for the problems class as long as you register and show up for more than 10 sessions.

In an effort to meet obligations under Title IX, UNM faculty, Teaching Assistants, and Graduate Assistants are considered “responsible employees” by the Department of Education (see pg 15 - http://www2.ed.gov/about/offices/list/ocr/docs/qa-201404-title-ix.pdf). This designation requires that any report of gender discrimination which includes sexual harassment, sexual misconduct and sexual violence made to a faculty member, TA, or GA must be reported to the Title IX Coordinator at the Office of Equal Opportunity (oeo.unm.edu). For more information on the campus policy regarding sexual misconduct, see: https://policy.unm.edu/university-policies/2000/2740.html
