Course Prerequisites:  Physics 325 Electricity and Magnetism I

Required text:  Introduction to Electrodynamics, David Griffiths, 3rd edition (available at Text Rental)

Other materials: You will need a calculator and a table of integrals. You may purchase a table of integrals from the bookstore. You may order a larger math handbook like the one I use or you may choose a smaller, less expensive Pocket Book of Integrals by CRC press. You may also wish to purchase Div, Grad, Curl, and All That by H. M. Schey, a helpful reference on vector calculus.

Course Description: This course will concentrate on chapters 5-7, 9, and 11 of the text, and has the following objectives:

  • Continue to hone mathematical skill in vector calculus and other advanced methods.
  • Understand and predict behavior of time-varying fields.
  • Understand Maxwell's equations and the behavior of electromagnetic radiation.

This is the second semester of a two-semester course. It is not particularly more difficult than the first semester, but the problems it tackles are different because the fields are allowed to change with time.

Timeliness: Homework assignments are due by the beginning of class on the day I indicate. Assignments submitted within the next 24 hours will be graded at half credit and zero credit thereafter. Excuses for late assignments must be communicated to me before the assignment is due, either by phone, email, or a message to the department secretary. It is your responsibility to prepare and submit your assignments on time. Late exams are not allowed, but in special cases you may take an exam early.

Grading policy: The course grade is based upon homework assignments and five exams, weighted approximately as follows:

Exams: Midterm exams are tentatively scheduled to occur on February 15, March 8, and April 5.  They are all on Wednesday nights from 6:30pm to 8:30pm. The final exam, part of which will be comprehensive, is scheduled for Thursday, May 18, at 8:00 am.

Homework: Homework problems will be assigned regularly. You should not believe that the homework problems are sufficient practice for the exam. Instead I recommend that you work out a few additional problems for each chapter from the text, and work through some example problems in the text (actually writing it out is better than simply reading it). I have the complete solution manual to the text, and there are several other E&M texts in the library with other example problems, homework problems, and solutions. I highly recommend obtaining your own copy of an introductory physics text for reference and additional homework problems. Practice helps a lot!

Class Examples: You will be given two opportunities during the semester to earn 10 bonus points by presenting an example problem to the class.  I will tell you which problem you will be asked to solve about one week in advance.  You may choose to decline if you wish, and I will work the example for the class.  But if you decide to present the solution it will be a good way to really understand the topic; you never understand anything as well as you do when you try to explain it to other people!

Community Rights & Responsibilities:

Students with special needs should contact the Office of Disability Services during the first two weeks of the semester in order to request accommodation.  A Reasonable Accommodation Request-Report Form is available online.  Religious beliefs will be accommodated according to UWS 22.03 as long as the student notifies the instructor about the conflict within the first three weeks of class.  Students are expected to maintain the highest standards of academic integrity for their work in this course. The University of Wisconsin-Stevens Point dedicated to a safe, supportive and non-discriminatory learning environment. It is the responsibility of all students to familiarize themselves with University policies regarding special accommodations, misconduct, religious beliefs accommodation, discrimination and absence for university sponsored events.
