  • In addition, the class introduces and uses the following mathematics:
  • Vector calculus, including the curl, div, the Laplacian, Stoke's and Gauss' theorems.
  • Fourier series solutions to partial differential equations
  • Special functions, including Legendre Polynomials, Bessel functions
  • Lab
  • Experiments for this course are covered in Physics 308

    Overview

    This course is an intermediate undergraduate level course in classical electromagnetic theory. The major topics for Physics 322 include electrostatics, magnetostatics, electromagnetic induction, and an introduction electromagnetic waves. The main goal of the class is to introduce the students to the language and mathematical techniques used for solving problems of electromagnetic theory; it also prepares the students for advanced coursework in the physics sequence including optics, statistical physics and quantum mechanics, and also for advanced topical classes such as plasma physics, condensed matter physics. This course is the first physics course in the undergraduate sequence to heavily use vector calculus for solving problems. As such, it is useful to have taken or be concurrently taking Math 321 and Math 322. This class also is the first time that partial differential equations (Laplace's Equation) are solved systematically. Traditionally, the course is taught with three lectures per week and a weekly problem session.
