Course Outline

Electromagnetism provides a complete description of electric and magnetic forces, which determine all interactions between charged objects. Much of the material world consists of charged particles and the combination of the range and strength of electric and magnetic forces means that these are the dominant interactions which govern our everyday experience. Maxwell's unified description of electric and magnetic forces and the link that he established between electromagnetic waves and light were the crowning glory of 19th century physics. Much of our understanding of the physical world and our abilities for manipulating it stem from the body of work which he synthesized.

Physics 311 offers detailed coverage of the key concepts and techniques of classical electromagnetism, leading up to Maxwell's equations and using the full tools of vector algebra and calculus. One goal of this course is to expose you to the fundamental concepts and mathematical techniques of this theory, which plays an important role in theoretical discussions in most subfields of physics. But electromagnetism is more than a mere theoretical endeavor; it enters into the majority of experiments in the physical sciences. The second goal of this course is to equip you with the theory which is crucial for understanding and managing experimental and applied aspects of the physical sciences.

Supplementary Reading

There are many additional texts which are potentially suitable for this course. The following is a selection.

1. Electromagnetism

   1. R. P. Feynman, R. B. Leighton and M. Sands, Lectures on Physics, Vol II, Addison-Wesley (1965).

      Pitched somewhere between a sophomore and junior level text, this is still a classic. Feynman was renowned for his unique approaches at explaining physics.

   2. P. Lorrain, D. R. Corson and F. Lorrain, Fundamentals of Electromagnetic Phenomena, Freeman (2000).

      Another standard undergraduate level text.

   3. R. K. Wangsness, Electromagnetic Fields, Wiley (1986).

      Similar to other undergraduate electromagnetism texts but includes a chapter on waveguides.

   4. L. Eyges, The Classical Electromagnetic Field, Dover (1972).

      More of an introductory graduate level text but sections are still accessible to an undergraduate audience. This is generally an excellent text.

   5. A. Zangwill, Modern Electrodynamics, Cambridge University Press(2012).

      Excellent graduate-level text.

   6. J. D. Jackson, Classical Electrodynamics, John Wiley (1998).

      The default graduate level text, probably more as a result of its scope than its explanatory qualities. Encyclopedic but frequently confusing coverage of everything to do with electromagnetism. Tortuous problems.
