Course Description:
This course is a calculusbased
introduction to E&M (electricity and magnetism) and optics. Topics
include Coulomb's
law (static electric forces), electric and magnetic fields,
potentials and potential energy, Maxwell's
equations, light, image formation, and diffraction. Some basic
electrical circuits will be discussed,
but we mostly leave this to electrical engineering courses. Here
we want
to emphasize the theory and concepts inherent in all electric and
magnetic
phenomena. This is a challenging course in that you must
continue applying what you learned in
PHYS 2311 (Mechanics and Thermodynamics) and your Calculus
courses.
A tentative calendar of topics is outlined below.

Lab:
The lab for this class is Physics 2351. There are 2
sections which both meet on Thursdays.
Labs will meet in Meyer 122. Your performance in the
lab has no direct effect on your grade in the lecture, however,
you will learn the material better if make a good attempt in the
lab.
You will have an
informational meeting with your instructor on the first week where you
will be assigned your first lab.
Grading:
Inclass 
Homework, attendance  25% 
Quizzes 
Quizzes (drop lowest score)  25% 
Exams  There will be two exams and a final.  50% 
Total 
100% 
Your final letter grade is calculated roughly as follows:
<55  5570  7080  8090  90100 
F  D  C 
B 
A 
I will not grade any "harder" than the above. However, if the class mean drops below 75, I will grade more leniently.
Other Course Policies
Attendance will sometimes be taken. Attendance is crucial on exam days, quiz days, or due dates. Absences can also indirectly lower your grade because the material presented in class reflects the material on quizzes and exams. Let me know in advance (email is good) if you plan to miss for a valid reason (e.g. your team is on the road, you are sick, you have a family emergency). If you miss a quiz or exam because of an unforeseen emergency, let me know as soon as possible, and provide proof of the emergency. The name and phone number of a relevant authority figure (perhaps a parent) can be provided as proof.
Homework will consist of reading and working problems from the textbook. Problem solving is a major part of physics and so we will use some classtime each week (usually Friday) for group work on problem sets. **I hope to provide some practice exam questions from the test bank each week. These do not have to be turned in, but can be considered a homework "supplement". ** Homework turned in after 5 PM on the due date (usually Monday) will be given 50% credit. If you foresee yourself missing a deadline because of an excusable absence, again, let me know ahead of time.
Quizzes will usually be given on Mondays after nonexam weeks. They will consist of 5  10 questions, mostly multiple choice or short answer. They cover the assigned reading and especially the material discussed in class. You can only make up a quiz that was missed because of a valid conflict or emergency. Also, you can only make up the quiz before the answers are revealed (usually the next day). For this reason, I will drop your lowest quiz score.
Exams will be given roughly every 5 weeks (so that there are 2 plus a final). These will weigh most heavily towards your class grade. The final exam will be comprehensive, but will emphasize the last 35 weeks of material.
Disruptions You can ask questions during class, but don't interfere with the learning of the students around you with irrelavent chatter. Also, don't operate cell phones or laptops without my permission during lectures. Try not to arrive late or get up and walk out early (unless you are told to for being disruptive).
Academic Misconduct The College of A&S has a Code for Academic Student Conduct and forms for reporting students. Academic integrity is one of the basic principles of a university community. Ohio Northern University encourages and expects the highest standards of academic honesty from all students. The A&S code states that cheating, plagiarism, and other forms of academic dishonesty are subject to disciplinary action. In PHYS 2321 (this class), the biggest temptation will be to look at another person's work during tests. Do not wear caps during quizzes or exams or store information on electronic devices. Another temptation will be copying the homework solutions out of a manual. If I see cheating, I will give a zero score for that quiz or exam.
Calculators I encourage you to use a calculator in this class. However, you may not use calculators to store information for tests and quizzes. (This includes writing equations on the lid.) Tests and quizzes don't usually require much arithmetic, so the calculator is mostly needed for homework.
Tutoring will be available from the Physics Dept and Engineering sources. Listen for announcements in class. Of course, you are welcome to drop by during my office hours!
