Equation sheet for 323 (also 322 and 321) Web sites for 321 and 322
Examples classes: Each week the TA works through problems illustrating concepts from the MWF classes. Solutions will not be posted. Examples classes are an integral part of the course, being the fourth class of the week in this 4-credit course.
Office hours: In addition to "official" office hours I guarantee to be happy to help you any time you find me in my office, B432.
Study with the TA: These are gatherings of students to work on the homework or other problems with the help of a TA.
Books: our primary text is Introduction to Electrodynamics, by David J. Griffiths, (Prentice Hall, 1999, used paperbacks from $12). You can't learn a subject properly from a single text book. Please refer frequently to other texts. The problem with Griffiths' book is that it pretends the rest of physics, science and technology doesn't exist.
Homework is assigned weekly and due on Friday in class. In multi-part book questions do all parts unless otherwise stated. The solutions will be made available on this site immediately after that class. Late submissions should be brought to me in person. Homework left in my mailbox will not be graded. If you are likely to miss the deadline, email me your reason before the deadline so a special arrangement can be made. Discussing the problems with others is fine but you must turn in your own solutions. It is obvious when someone copies out standard solutions and it is noted and penalized. In homework grading, only some of the problems will be carefully graded; the rest will be checked. Some marks will be given for clarity of presentation. The total score in all homework sets is one of the five units of which the best four will determine your final grade. Bonus questions are recommended for self-study or talking to the prof and TAs about, and no credit is associated with them.
Exams: Midterm 1 and Midterm 2 are two of the five course grading units. The Final is another two units. Examination dates are given on the schedule page. They all start at 20 past the hour. Exams are closed book and closed notes, and no calculators (here's why). You are expected to know the relevant equations from the equation sheet, and you will get points for this memory feat.
Final grade calculation: In calculating your final score, the weakest of the five units - either one midterm score, half of the final exam score, or the homework - will be dropped. So if you mess up one midterm or don't do any homework you can still get a high grade if you do well in everything else. The median final grade is likely to be 3.2.
Web pages: Keep an eye out here for announcements, homework, new resources, and surveys. The class schedule will be updated as we go.
Goals of the course: The student should gain understanding of magnetism, both in its own right and as an introduction to field theory in physics. Heavy emphasis will be placed on problem solving, and mathematical methods learned in previous maths and physics courses will be employed. Successful completion of the course should result in a student gaining a professional ability to solve a wide variety of technical problems involving partial differential equations. We shall also discuss some modern physics topics within the context of electromagnetism.
