Course Prerequisites:  Physics 250 University Physics II, Math 220 Linear Algebra and Differential Equations, and Math 222 Analytic Geometry and Calculus III.

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 cover approximately the first 5 chapters of the text, and has the following objectives:

  • Learn and apply vector analysis and vector calculus to electrostatics and magnetostatics problems.
  • Learn and apply various techniques for calculating electric potentials.
  • Understand the behavior of electric and magnetic fields in materials.

This is the first semester of a two-semester course. Electricity and magnetism involves a lot of math with little real-world application. For instance, you might work 3 hours calculating the field due to a nonuniformly charged sphere, but how many nonuniformly charged spheres exist in real life? Therefore, in order not to get either bored or overwhelmed by this course, you should change your mindset a little: instead of expecting the course to increase your understanding of the world around you, expect it to teach you to use advanced math to solve electrostatic problems. Not only will these methods be useful to you when you work out future (graduate school) electricity and magnetism problems, but many of the methods are also used in other subject areas. The course will definitely sharpen your calculus skills as well.

Attendance: 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 scheduled to occur on September 28, October 19, November 9, and November 30. These dates may change but it's not likely.  They are all on Wednesday nights from 6:30pm to 8:30pm. The final exam, part of which will be comprehensive, is scheduled for Tuesday, December 20, at 2:45 pm.

Homework: A few example 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!
