**Grader: **Adam Zeitlin

**Textbook:
"**Electricity
and Magnetism", E. Purcell & D. Morin, 3rd edition. The lectures will
not follow the book closely and the book (either edition) is only recommended,
not required. The level of mathematical sophistication required in this class
is somewhat above what most students start the semester with. I will try to
help you with multivariable and vector calculus during the semester and a good
source for these topics is the free, online textbook "Mathematical Tools
for Physics", by J. Nearing, that can be found here. Chapters
8, 9 and 13 are the relevant ones.

**Grades:** The grade will be based on frequent homework (10%), and
three in-class exams (30% each).

**Syllabus
and objectives: **The goal of this class is to introduce the concept of
electromagnetic fields and the mathematics used in their description,
understand the laws governing them (Maxwell's equations) and apply these laws
to a large variety of situations arising in several branches of physics,
astrophysics and technology. The specific topics covered and the level of
sophistication will be comparable to Purcell's book but it's unlikely we will
be able to cover all chapters, in which case we will skip most of electric
oscillating current circuits (discussed in depth in PHY273), dielectrics and
magnetic materials.

Some people like " Div, Grad, Curl, and All That: An Informal
Text on Vector Calculus", Fourth Edition, H. M. Schey.

Make sure you play with the applet to find the field
configurations generated by different charges distributions. It is the best way
to get some intuition for the Coulomb law. There are other, better versions
around the web. Let me know if you find a particularly good one.

**Academic
Integrity: ** The University of Maryland, College Park has a nationally
recognized Code

of Academic Integrity, administered by the Student Honor Council. This Code
sets standards for

academic integrity at Maryland for all undergraduate and graduate students. As
a student you

are responsible for upholding these standards for this course. It is very
important for you to be

aware of the consequences of cheating, fabrication, facilitation, and
plagiarism. For more information on the Code of Academic Integrity or the
Student Honor Council, please visit
