# Physics 303

Classical fields / Electrodynamics

**Syllabus, Spring 2012**

We meet at **noon, MWF in SC 203**.

### On the web

You can find the syllabus and other materials related to
this course on the web at:

**goshen.edu/fields** , or

**goshen.edu/physix/303** .

Grades will be available on moodle.goshen.edu.

I use **your "goshen.edu" e-mail address** for class communications.
Some of you may use other e-mail services. If you *do* use some
other service, make sure your goshen.edu e-mail account is set up to

### Overview

The classical theory of electric and magnetic fields is developed using vector calculus. Topics include dielectric and magnetic materials, Maxwell's field equations, and electromagnetic waves. Prerequisites: Phys 203-204-General Physics I and II.

This is a 3 credit hour course. The College expectation is that you are spending 2-4 hours outside class for every hour in class.

### Texts and Tools

#### Required

David J. Griffiths. *Introduction to Electrodynamics* (3rd edition). Prentice Hall, 1999.

*Mathematica*:
You'll need to use a computer algebra system like *Maple* or *Mathematica* to
visualize and solve some homework problems and potentially exam questions.
You don't have to buy one: GC has a site license for *Mathematica* which
is available on GC lab computers.

### Grading

homework |
28% |

problem writeups (2) |
8% |

2 exams |
38% |

final exam |
23% |

participation |
3% |

Total grade outcomes:

- A > 90%

B 80-89%

C 70-79%

D 60-69%

F < 60%

I *may* adjust this scheme down a bit (e.g. 89% might end up being good enough for an A), but I certainly won't adjust it up.

#### Homework

Working through the homework is perhaps more important for your learning than anything we do in class. Everyone will hand in their own write-up of each homework problem. But I encourage you to work through homework problems with others in the class.

Unless otherwise indicated, problems are from Griffiths' textbook.

#### Disability accommodations

Goshen College wants to help all students be as academically successful as
possible. If you have a disability and require accommodations, please contact
the instructor or Director of the Academic Resource and Writing Center, Lois
Martin, early in the semester so that your learning needs may be appropriately
met. In order to receive accommodations, documentation concerning your disability
must be on file with the Academic Resource and Writing Center, GL113, x7576,
lmartin@goshen.edu. All information will be held in the strictest confidence.
The Academic Resource and Writing Center offers **tutoring
and writing assistance for all students**. For further information please see www.goshen.edu/studentlife/arwc/.
