General Information

Recommended Text:

• Classical Electrodynamics, by J. D. Jackson 3rd edition
  • This is THE standard text. The authority on statics, but less so in dynamics.

Other Texts:

• The Classical Theory of Fields, by L. D. Landau and Lifshitz
  • They must have been short of paper in the Soviet Union when this book was written, but if you can decompress it, there's lots of good stuff.
• Electromagnetic Theory, by J. A. Stratton
• Classical Electricity and Magnetism , by W. K. H. Panofsky and Phillips
  • Two somewhat old fashion, but good texts.
• Introduction to Electrodynamics, by David Griffiths
  • An upper division undergraduate text (used in Phys. 405-406). Very clear.
• Electricity and Magnetism (Second Edition), by E. M. Purcell
  • One of the most beautiful "elementary" treatments, but still a classic.

Grading:

• Problem Sets: 40%
• Two Take-Home Exams 40%
• Final Exam (In class): 20%

Problem sets will be distributed in class, about once a week. Assignments will be due on Friday in the grader's mailbox by 5:00 PM.
