Handout on spherical coordinates, Legendre and associated Legendre polynomials, and
spherical harmonics:
Although spherical harmonics are familiar through various courses including quantum
mechanics, we generally get much less exposure to the

The overall objectives of PY785 are (1) to emphasize the importance of basics in
setting up and solving problems, and (2) to develop skills for doing this (3) in
electrostatics and magnetostatic
Magnetics.
Jackson does a good classical treatment of magnetostatics, but in the lectures I brought
in some additional material, so it seemed reasonable to write up the notes.
As we discussed, magnetostatics is intrinsically different from electrostatics

In the last part of the course, we considered topics that Jackson covers in Ch. 5, mainly
magnetostatics, with some material on energy added from Ch. 6. Jackson does a fairly
complete formal job
Chapter 6: Maxwells Equations, Gauge Transformations (12 Feb 8:08 am version)
Jacksons Ch. 6 was clearly designed by a theoretical physicist rather than an applied
physicist. In any case his work is impressive. It is thorough, even if a bit esoteric, a te

Chapter 7 covers a combination of topics, including the coherent and incoherent
superposition of plane waves, reflection and transmission, properties of the dielectric
function, and interference. It provides the foundat
What someone skilled in grad-level E&M should know, PY786 (25 Feb 2014)
My primary goal is to convince you of the importance of using basic equations to understand
physical phenomena. Well also learn some E&M along the way.
