PHY 272 (PHY 272 H)- Spring 2016
Instructor: Luis A. Orozco, Computer and Space Science Building, room 2201,
phone (301) 405 9740, email: lorozco@umd.edu
Class hours: TuTh 12:30pm - 1:45pm,
F 12:00 pm - 12:50 pm
Classroom: Toll Physics 1201
Office hours: Monday 4:00 to 5:00 PM, Tuesday 10:00 to 11:00 AM
Honors students: We will set another session per week for further discussions.
Grader: TBD
Textbook: "Electricity and Magnetism", E. Purcell & D. Morin, 3rd
edition. The lectures will follow the book closely, but not exactly, and the
book is highly recommended; if you buy it you can go back to it in the future
as a source of physics understanding and intuition. The level of mathematical
sophistication required in this class is somewhat high. We will see many
concepts that show the strong connection between Physics and Mathematics.
General familiarity with vectors and their operations is expected at the
beginning of the course, and during the course you will have to develop an
understanding of vector calculus and multivariable calculus. A good source for
these topics is the free, online textbook "Mathematical Tools for
Physics", by J. Nearing, that can be found here. Chapters 6, 8, 9, and
13 are the relevant ones.
Grades: The grade will be based on frequent homework (20%), due on
Fridays at the beginning of class, and four partial exams (20% each). I will
drop your lowest grade out of the five components (homework and four exams) to
calculate your final grade.
Syllabus and objectives:
The goal of this class is to introduce
the 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 is unlikely we will
be able to cover all chapters. We will skip most of electric oscillating
current circuits (discussed in depth in PHY273), dielectrics and magnetic materials.
The study of fields of moving charges with be mostly qualitative. The homework
will have problems from the textbook and some from outside. The level of
difficulty will be higher than you have had in the past.
