The goal of
this class is to introduce the subject of classical
electromagnetism at the advanced undergraduate level.
Classical electromagnetism (EM) is fundamentally a
local theory of vector fields and its proper treatment
requires methods of vector analysis and differential
equations. We will briefly review these mathematical
concepts in the first few lectures of the class. In
this class, we will entirely focus on static
(time-independent) fields interacting with charges at
rest or in steady motion. In this case, the electric
and magnetic fields decouple from one another so they
can be treated independently. Such independent
treatment of electrostatics and magnetostatics is the
central content of this class.
A sizable fraction of this class will be spent
computing the electric field and potential created by
a static distribution of charges. We will also discuss
how the electric field behaves within conductors and
insulators. The second part of the class will be spent
computing magnetic field resulting from static
currents, including how the magnetic field behaves in
the presence of insulating matter. Time-dependent
electric and magnetic fields created by moving charges
and nonsteady currents will be covered in the next
Electricity and Magnetism course, PHYS 406.
The final exam will take place
on Thursday May 13 at 9am on UNM Learn.
To access the Zoom links
below, you will need to log in with your UNM Net ID.
The Zoom meeting password will be emailed to you at
the beginning of the semester.
Tuesdays and Thursdays, 1:00-2:15pm on Zoom. If the COVID
situation improves and students are comfortable coming
to class, we might meet in PAIS 1140. If you don't
hear from me, assume that the class will take place
online.
Instructor
Tuesdays 3:00-4:00pm and Thursdays 10:00-11:00am on Zoom. These are my preferred
"office" hours. If you can't make my regular office
hours, or if your questions cannot wait, please send
me an email to set up an appointment.
Teaching assistant
The teaching assistant is Ali Kazemi (akazemins@unm.edu).
He will be available on Thursdays 3:30-4:30pm for
you to call in (Zoom)
and discuss any homework grading issues you may
have. If you need to schedule an appointment outside
of the TA's office hours please send him an email.
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:
Homework: the best 10 scores of the 11
assignments will represent the 20% of the final
grade.
Two midterm exams: each of them will represent the
25% of the final grade.
Final: will represent the remaining 30% of the
final grade.
The midterm exams are tentatively scheduled for
February 18 and April 1 during
(extended) class time, and the final exam will be held
during exam week.
Homework assignments
There will be 11 assignments during the semester.
The assignments will be posted in the tentative schedule
about 7-10 days before they are due. The login
information necessary to access the homework PDFs
will be provided in the first class. The homework must be submitted on
the UNM Learn
platform at 5pm on the day they are due.
Late homework policy: homework returned in the next
24 hours after the due date will be accepted but
with 25% penalization. After these 24 hours the corresponding
solutions will be posted here, and
homework assignments submitted after solutions
post will not be graded.
While I strongly
encourage you to discuss the homework
assignments with your classmates, the work you
hand in must be entirely yours.
Problems class
Listed officially as
PHYS 415, this is a very
important adjunct to the main lecture class, taking
place every Fridays from 9 to 9:50am on Zoom.
It will provide you additional practice with solving
problems beyond the homework assignments and self
study. 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
on the Wednesday 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. Even if you don't register for the
class, I encourage you to attend anyway, just to get
the extra practice.
In accordance with
University Policy 2310 and the Americans with
Disabilities Act (ADA), academic accommodations may be
made for any student who notifies the instructor of
the need for an accommodation. It is imperative that
you take the initiative to bring such needs to the
instructor’s attention, as I am not legally permitted
to inquire. Students who may require assistance in
emergency evacuations should contact the instructor as
to the most appropriate procedures to follow. Contact
Accessibility Resource Center at (505) 277-3506 for
additional information.
If you need an accommodation based on how course
requirement interact with the impact of a disability,
you should contact me to arrange an appointment as soon
as possible. At the appointment we can discuss the
course format and requirements, anticipate the need for
adjustments and explore potential accommodations. I rely
on the Disability Services Office for assistance in
developing strategies and verifying accommodation needs.
If you have not previously contacted them I encourage
you to do so.
Each student is expected to maintain the highest
standards of honesty and integrity in
academic and professional matters. The University
reserves the right to take disciplinary action, up to
and including dismissal, against any student who is
found guilty of academic dishonesty or otherwise fails
to meet the standards. Any student judged to have
engaged in academic dishonesty in course work may
receive a reduced or failing grade for the work in
question and/or for the course.
Academic dishonesty includes, but is not limited to,
dishonesty in quizzes, tests, or assignments; claiming
credit for work not done or done by others; hindering
the academic work of other students; misrepresenting
academic or professional qualifications within or
without the University; and nondisclosure or
misrepresentation in filling out applications or other
University records.
A Note About Sexual Violence and Sexual Misconduct: As a
UNM faculty member, I am required to inform the Title IX
Coordinator at the Office of Equal Opportunity
(oeo.unm.edu) of any report I receive of gender
discrimination which includes sexual harassment, sexual
misconduct, and/or sexual violence. You can read the
full campus policy
regarding sexual misconduct. If you have
experienced sexual violence or sexual misconduct, please
ask a faculty or staff member for help or contact LOBORESPECT.
Citizenship and/or Immigration Status:
All students are welcome in this class regardless of
citizenship, residency, or immigration status.
Your professor will respect your privacy if you choose
to disclose your status. UNM as an institution has made
a core commitment to the success of all our students,
including members of our undocumented community. The
Administration's welcome is found on our website.
