Lecture Instructor's Comments

  • Welcome to the second quarter of three Electricity and Magnetism courses at the University of Washington. You should find this course quite challenging, and the expenditure of time required to fully grasp the subject should be high. That said, you should also find that your mathematical and physics abilities greatly increased by the effort.
  • Classical Electromagnetic theory is one of the great stepping stones to modern physics, thus this class lays the foundation for more advanced classes. In particular, A. Einstein's work in electrodynamics led him ultimately to his Theory of Relativity.
  • Maxwell's collection of equations is also a powerful example of what is known as a unified theory. In this case it connects the electric field with the magnetic field in a single theoretical framework. This model has proved to be one of the great achievements in human intellectual development.

General Comments

  • Given that this is Summer Quarter, there are several things to be aware of. One is that there are only nine weeks.


Grading Policy

The final course grade is based on the two midterms, HW, tutorials, and possibly lecture exercises. However, the lecture instructor may adjust individual final grades by no more than 0.2 grade points (about 5 % out of 4.0 possible) based on records from the lecture radio frequency response system and/or the supplemental homework related to the lecture. All percentages discussed in the policy statement and in the summary below are used to determine your raw grade, before this adjustment is applied.

  • Midterm exams: [20% ea] There will be two closed-book midterm exams. Each midterm will emphasize recent material, but may include questions dealing with topics from far earlier in the course. The exams will include both multiple choice and essay-style questions, as well as potential video submissions. After correcting for different average scores on different midterms, the midterms will contribute 40% to your final raw grade. You are permitted to bring one 8.5"x11" page of notes (front only) to each midterm. Calculators are permitted. Cell phones, radios, etc. are not permitted. Laptop computers are not permitted, and the use of the text-storage capability now available on many calculators is not permitted. 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.

  • Video exams submissions: As part of your exams and/or homework we may implement video submissions. You will solve problems and explain how you solved them. We will discuss more in class so please be sure to attend! Updates will be posted up here.
  • Note that there will be no make-up exams, unless sufficient advanced notice is given. Students with outside professional, service, or career commitments (i.e. military service, ROTC, professional conference presentation, NCAA sports, etc.) conflicting exactly with the exam dates must contact the instructor early in the quarter to establish alternate examination procedures.  Except for extreme circumstances, a final grade of 0.0 may be assigned to any student who misses two midterm exams.

  • Final Exam: There will be no "final exam" in the sense of a final cumulative exam of greater weight than other exams.

  • Exam Re-grades: If you believe that the points on the examination were incorrectly totaled or if there is a gross error in the grading, you may return an exam for regrading. To do so, you must resubmit the examination no later than at the beginning of the lecture following the one in which the exams are returned. You must write a brief note on the front page or attached to the front page of the exam explaining the possible error in the grading. Do not make *any* changes or marks on the other pages of the examination. Portions of each examination are scanned or photocopied. You should be aware that any request for a regrade may result in a regrading of the entire exam. Therefore your total score may increase or decrease.

  • Homework: [30%] Lecture homework will be assigned and collected weekly. It is to be turned in by the end of the day and will not be accepted late.  The absolute importance of homework in learning this subject cannot be overemphasized! Please note that for HW the most important aspect will be the work you show, not necessarily the answer. Particularly creative or novel approaches will be rewarded with higher scores.
    • Written Homework: for the written homework we are more interested in the work and not the answer. We plan to make the answer worth approximately zero points. You will likely need to explain, using English, why you took the steps you did solving problems. More info in class and we'll update here.
    • Video Homework: some problems we may require you to solve on video, explaining how you solved a problem. Format may vary; again, we'll discuss more in class and update here.
  • Tutorials [30%] Tutorial Webpage Tutorial pretests, tutorials, and tutorial homework will be done during the quarter. Tutorial pretests turn on Friday afternoon, and turn off Monday morning.  The tutorials will be every Monday, and the tutorial HW will be due the following Friday at noon, PDT. You will be graded on the pretest, on attendance in the tutorials, and on the tutorial HW. For details see the tutorial webpage.
  • Your responsibilty: Check your grades on Canvas every week or two and report any problems to the lecture instructor and tutorial instructor immediately. Exam and homework grades should be recorded for your review within one week from the date that papers are submitted for grading. Supplemental HW, if assigned, should be recorded every two weeks or so. Grading problems that are reported in a timely fashion will be investigated and, if action is warranted, corrected. The lecture instructor may choose to ignore grading complaints that are not reported in a timely fashion.


The Physics Study Center (Not available during Covid)

Students are encouraged to gather and work cooperatively in small groups in the Physics Study Center located in room AM018 of PAB. (to reach the Physics Study Center, go down the stairs that circle behind the Foucault pendulum and proceed toward the end of the hall). Teaching assistants will be available for consultation during many portions of the day if your study group needs assistance, but staffing levels will not support much individual attention. The Study Center is staffed from approximately 9:30am to 4:30pm on weekdays.

 

Class Policies

Attendance Policy: Since participation is vital for a successful experience, please arrive on time for class. Late arrivals interrupt our in-progress activities and discussions. If you must miss a class session, let the instructor know as soon as possible so that you can make up the work that you miss. DO NOT ARRIVE LATE TO CLASS!


Technology in the Classroom: Since technology is profoundly linked to education, there will be many times when I ask that you employ different tools in the gathering and expression of knowledge. Since, however, education is also
more than technology, please turn off all laptops, cell phones, iPods, etc before the start of class and I will let you know when we’ll make use of them. (There are exceptions for students with specific note-taking and other needs.)

Incompletes: University rules state that “an incomplete is given only when the student has been in attendance and has done satisfactory work until within two weeks at the end of the quarter and has furnished proof satisfactory to the instructor that the work cannot be completed because of illness or other circumstances beyond the student’s control.” We strongly discourage incompletes.

Online privacy:

This course is scheduled to run synchronously at your scheduled class time via Zoom. These Zoom class sessions will be recorded. The recording will capture the presenter’s audio, video and computer screen. Student audio and video will be recorded if they share their computer audio and video during the recorded session. The recordings will only be accessible to students enrolled in the course to review materials. These recordings will not be shared with or accessible to the public.
 
The University and Zoom have FERPA-compliant agreements in place to protect the security and privacy of UW Zoom accounts. Students who do not wish to be recorded should:
 
Change their Zoom screen name to hide any personal identifying information such as their name or UW Net ID, and Not share their computer audio or video during their Zoom sessions.
