Physics 406 Fall 14. Course Title: Electricity and
Magnetism II, Section 001, Call Number 45111,
Cr 03, TR 12:30-1:45 PandA 5, instructor is Dinesh Loomba, dloomba@unm.edu ,
office in room 131 of the Physics and Astronomy (P&A) Building at the
northeast corner of Lomas and Yale. The prerequisites for this course are
the successful completion of Physics 405 & Math 312.
________________________________________________________________________________
Text and other material. Mandatory Text: Introduction to
Electrodynamics by David Griffiths, 4th ed. The problem
session (Physics 416 section 001) should be helpful but is not required. In addition, as the course proceeds
I’ll add material below on supplementary topics (either reading or notes).
________________________________________________________________________________
Office hours and TA help. My office hours will be M, 11-12 in room
131, and Th 12-1 in room 131 or 184. Wednesdays 1-1:50 in room 184 I will be
teaching the problems session and you are welcome to drop by to ask questions
or do problems. You can also make an appointment. The TA is Ms.
Xijie Xuo and her office hours are T 4-5PM, Th 2-3PM in the PandA lobby.
________________________________________________________________________________
Grading: The grading in the course will be based on performance in homework (HW) assignments (30%), approximately 5 exams (70%), and an optional cumulative final exam (30%). There will be 10-12 assignments in all with about 4-5 problems each. You are encouraged to collaborate, but your final solutions should be independent. Each exam will be closed book, but I will provide some equations/information in each exam.

Approximate Schedule of Topics
· Finish
Electrodynamics & review Semester 1 (Reading: Finish Chapter 7)
Last semester we covered EMF (7.1), Faraday’s Law of induction (7.2), and the Maxwell-Ampere Law and the complete Maxwell’s equations (7.3).
Please review all of this as I will only briefly
summarize it. This semester
we’ll fill out these sections, focusing on self- and mutual-inductance (7.2)
and a few other topics in the Chapter
· Conservation Laws (Reading: Chapter 8)
Charge and energy
Linear and angular momentum
· Electromagnetic Waves (Reading: Chapter 9)
Waves in one dimension
EM waves in vacuum
EM waves in matter and at boundaries
Absorption and dispersion
Waveguides
· Potentials and Fields
Scalar and vector potentials
Continuous distributions and retarded potentials
Moving point charges, Lienard-Wiechert potentials, and EM fields
· EM Radiation
Electric and magnetic dipole radiation
Radiation from an arbitrary source
Power radiated by a point charge
Radiation reaction and damping
· Electrodynamics and Special relativity
Special theory of relativity
Relativistic electrodynamics
