<p>GENERAL</p>
<p>Physics 4202 is the basic Electromagnetism course for students majoring<br />
in Physics or a related subject. It is typically taken by seniors or juniors.<br />
It is required for physics majors, and useful also for students in may<br />
other areas in science and engineering.</p>
<p>This Syllabus includes important information about the course: students<br />
are responsible for knowing its contents and should read it thoroughly.</p>
<p>PREREQUISITES</p>
<p>The freshman and sophomore Physics sequences or their equivalent, are required. Knowledge <br />
of elementary Special Relativity at the level of PHYS 2503 is<br />
desirable. It is useful for students to be familiar with Classical<br />
and Quantum Mechanics at the 4-level, but this is not required. <br />
Knowledge of mathematical techniques at the usual level<br />
for an upper division Physics student is expected, including<br />
Calculus, Linear Algebra and simple differential equations. Knowledge<br />
of Fourier analysis would be very useful. Some more<br />
advanced mathematics will be introduced in the course itself. Some<br />
knowledge of programming (C++, Fortran) or symbolic (Mathlab, Mathematica...) <br />
languages will be useful, but no sophistication in these things is expected.</p>
<p>Students contemplating taking the course who are not sure<br />
they have the background, or who formally are lacking any<br />
prerequisite should consult with the Instructor. Special permissions will be <br />
very liberally granted to all willing to do some extra work.</p>
<p>GENERAL</p>
<p>The course includes three lectures and one recitation session a week. There<br />
is no lab associated with the course. </p>
<p>HOMEWORK AND PROBLEM SOLVING</p>
<p>The homework is the fundamental tool you have to learn the problem solving<br />
skills that you need to really understand Electromagnetism. Basically<br />
all of your grade (as you will see below) will be assigned based on <br />
problem solving. If you think you understand the book and the lectures but <br />
cannot solve the problems, then you do not really understand the material. <br />
On the other hand, attempting to solve the problems will help you a lot <br />
in reaching a true understanding of the material. </p>
<p>Homework will be assigned weekly every Tuesday (Wednesday for the first<br />
week), and be due one week after. <br />
No late homework will be ever accepted. Some of the assigned <br />
problems will be discussed and solved in a group situation at the recitation<br />
session the Thursday after the problems are assigned. Each student, however,<br />
should hand in his or her own version. </p>
<p>Homework will be graded. If illness or other valid reason prevents you from <br />
doing a set, an adjustment <br />
will be made in the denominator of your homework percentage. <br />
Sample solutions will be posted at the course <br />
Canvas or Web site.</p>
<p>In addition to the recitation session work, students are encouraged<br />
to work with other people on the homework, as an informal group. <br />
In group situations, make absolutely sure that you pull your<br />
own weight and that you understand everything on your own terms. By the<br />
same token, be ruthless to expel any freeloaders from the group, if there<br />
should be any: you'll be doing them a favor in the long run. Remember that<br />
ultimately your grade, and in the long run your success as a scientist or<br />
engineer, basically depends on your ability to solve problems<br />
individually.</p>
<p>Attempting all the homework is so important that the grade formula for <br />
the course, as explained below, makes it essentially mandatory. "Attempting"<br />
is of course not the same as "solving correctly": it means trying to.</p>
<p>Handing in solutions copied from another person, or found in the web, would,<br />
be, besides cheating, evidence of lack of interest<br />
in learning, and of inability to keep minimum professional standards:<br />
it would be dealt with accordingly with great severity. </p>
<p>The assigned homework is the minimum amount of practice exercises students<br />
should do. All are encouraged to solve as many additional problems (from<br />
the book or other sources) as possible.</p>
<p>LECTURES AND OFFICE HOURS</p>
<p>Lectures are MWF at 3:35 in room Tate 110. Attendance is very highly<br />
recommended, although not strictly mandatory: however,<br />
students are responsible for all that is said in class. Attendance to<br />
the recitation counts for the grade. There are<br />
office hours by the instructor in Tate 130.25 Wed 4:30 to 5:15, and by the TA rigth after the recitation, in Tate 201-09.</p>
<p>TEXTBOOK AND OTHER BOOKS</p>
<p>The official textbook for the course is Griffiths, "Introduction<br />
to Electrodynamics", fourth edition. If you are broke find a<br />
used copy of a previous edition (but note that numbering of equations and<br />
problems may be slightly inconsistent). You should count on keeping this book<br />
after the course, do not resell it: workers do not sell their good tools. </p>
<p>The textbook is deceptively thin: many steps are skipped (some of those<br />
will be covered in the lectures) and students are expected to work them <br />
out on their own: do so. You may find this difficult at first, but in the long run <br />
it'll be good for you. The textbook will be followed relatively<br />
closely, but not slavishly so. Examples as in the book, or <br />
similar ones, will be discussed in class. </p>
<p>If you can, buy also another book for extra reference. No specific 'second<br />
book' can be recommended for everybody. The rule is:<br />
if you find yourself always borrowing the same book from a friend, or<br />
the Library, because you like the explanations in that book better than<br />
Griffith's, then you should buy your own copy. <br />
There are many other Electromagnetism books; just do a google<br />
search. They are of various levels<br />
of difficulty. Jackson and Panofsky&Philips are graduate level. Saslow's<br />
is more elementary than Griffiths and has many interesting insights.<br />
Reif and Milford is an old classic...<br />
Keep also handy your 2503 book in case you have to review<br />
anything. The same goes for your math books. Also, you need Tables to look<br />
up integrals, series, or special function properties. Do not waste time<br />
doing computations for which you can look up the answer. If you have access to<br />
a symbolic package such as Mathematica, these are built-in: the textbook<br />
recomends Mathematica. In hard copy, the <br />
Gradshtein-Ryzhik "Tables" and the Abramowitz-Stegun "Handbook of special <br />
functions" are the holy writ.</p>
<p>MATERIAL COVERED</p>
<p>We will cover approximately the first seven chapters<br />
in the textbook. There will be a little more emphasis<br />
than in the book on the properties of actual materials as opposed to<br />
'in vacuum' electromagnetism. Most of the math material in Chapter 1 will<br />
be covered at the point where it is first needed, not at the beginning.</p>
<p>Always read, before a lecture, the material in the book that you expect<br />
will be covered in that lecture. You should expect to find some parts<br />
too difficult to understand on your own: that's where you must pay<br />
extra attention, and ask questions, during the next lecture. Take notes<br />
in class and read and edit them within 24 hours: this transfers information<br />
from your short-term memory to long-term. </p>
<p>EXAMS</p>
<p>There will be one one-hour midterm, on October 26. There will be a three-hour final on December 18 4-7 pm,<br />
a date and time <br />
determined by the Department. A make up final will be given only in <br />
the cases where it is strictly required by University rules. There will be no <br />
midterm makeups: students having a legitimate excuse as per University rules<br />
will have the denominators of their exam percentage adjusted properly.</p>
<p>All exam questions will be problems, with a range of difficulty and<br />
scope similar to that in homework.</p>
<p>GRADES</p>
<p>The grades will be determined by two factors: </p>
<p>The regular portion of the grade, R, will be composed of: successful homework<br />
solutions (30% weight), the midterms (30% weight total) and the final (40%<br />
weight). R is expressed as a percentage.</p>
<p>The second, participation, P, grade will be computed as<br />
follows: 80% from the number of homework problems you have seriously<br />
attempted (seriously attempted means you have handed in<br />
a solution showing substantial work, you will get credit<br />
even if your solution was 100% wrong) <br />
10% from your class participation (asking questions etc) as judged by the<br />
instructor and 10% from your dattendance and participation<br />
in the discussion session,<br />
as judged by the TA. A diligent student should find it <br />
rather easy to get a P near 100%. </p>
<p>The overall grade T is determined by the square root of P times R. <br />
T=sqrt(R*P). This means for example, that a student getting P=1 (100%) which <br />
is quite doable, and a regular "exams and homework" grade of 64% (a C <br />
according to the formula below) would have<br />
it transformed into 80% (a B/B+). Students<br />
not attempting the homework are, on the other hand, guaranted an F.</p>
<p>Letter grades will be based on overall grade T with 5% intervals corresponding<br />
to +/- increments, that is 15% increments corresponding to every letter. <br />
Thus, you need 40% to get a D-, 55% to get C-, 70% to get B-, 85% to get A-.<br />
This scheme awards A+ to students getting 95% or higher. The University, for<br />
some bizarre reason, does not recognize the A+ grade, students earning one will<br />
have a plain A in their official transcripts, but will receive a<br />
congratulatory email from the Instructor (which they can frame if they wish). <br />
Students taking the course on an S/F basis must earn at least a C-, a D level grade<br />
is not satisfactory.</p>
<p>INFORMATION</p>
<p>The course is on CANVAS. There is also a web page in the Physics Deaprtment,<br />
see <a href="https://www.physics.umn.edu/classes/phys/2018/fall/Phys%204002.001/index.html">https://www.physics.umn.edu/classes/phys/2018/fall/Phys%204002.001/index.html</a></p>
<p>Brief solutions to each homework set will be posted in one place or<br />
both, depending on what works, in .pdf format. Other information about the <br />
course will be posted there.</p>
<p>Students should periodically check the site, as they are responsible<br />
for knowing the course announcements and other information posted.<br />
</p>
<p>OFFICIAL WARNING</p>
<p>No cheating or other unprofessional behavior will be tolerated. The minimum<br />
penalty for cheating is an automatic F for the course. All cases will be<br />
considered for whatever maximum the Supreme Court allows.</p>
<p>OTHER STUFF (LEGAL):</p>
<p>For anything not covered above, all relevant University Policies will be <br />
followed. A very comprehensive index of such policies is at <br />
