Textbook

The course text will be "Introduction to Electrodynamics" by David J. Griffiths (Prentice Hall, 3rd Edition, 1998), available in the bookstore. We will cover the material in Chapters 1-7 in this course (although in a different order: see the outline below), the remaining chapters are useful for PHYS 352 Electromagnetic waves.

There are many other books on electromagnetism to look at. "Electromagnetism" by Gerald Pollock and Daniel Stump (Addison Wesley, 1st Edition, 2001) is a newer book, slightly more formal than Griffiths, and with more discussion of practical applications. Also, I recommend dipping into "Feynman Lectures Volume 2" (Addison Wesley Longman 1970), particularly for its physical insight.

The lecture notes will be made available on WebCT shortly after each lecture.

Outline

Electrostatics in vacuum (Griffiths chapter 2). Coulombs law and the principle of superposition. Gauss's law and applications. Electric potential and the curl-free nature of the electric field. Energy in the electrostatic field. Boundary conditions. The electric dipole.

Magnetostatics in vacuum (chapter 5). The Lorentz force and Biot-Savart law. Ampere's law and magnetic fields of current configurations. Magnetic energy.

Electric fields in conductors (chapter 3). Techniques for solving electrostatic problems: the uniqueness theorem, method of images, separation of variables.

Electric fields in matter (chapter 4). Dielectrics. Polarization and bound charge. Boundary conditions for the displacement field. Capacitors.

Magnetic fields in matter (chapter 6). Magnetization, dia- and paramagnetism. Boundary conditions for magnetic fields.

Electromagnetic induction and its applications/manifestations (chapter 7). Electromotive force. Faraday's and Lenz's laws. The displacement current and Maxwell's equations.

Evaluation:

Problem sets 20%, term paper 20%, and either (1) midterm 20%, final exam 40%, or (2) final exam 60%, whichever gives you the best grade. More information on the term paper can be found here. The midterm will be held in class on October 26th.
