CLASSICAL ELECTRODYNAMICS for Undergraduates

The gradient of a function is most easily visualized for a two dimensional finction φ(x, y) where x and y are the latitude and longtitude and φ is the height of a hill. In this case surfaces of constant φ will just be like the contour lines on a map. Given our discovery above that the direction of the gradient is in the direction of steepest ascent and the magnitude is the slope in this direction, then it is obvious that if we let a smooth rock roll down a hill then it will start to roll in the direction of the gradient with a speed proportional to the magnitude of the gradient. Thus the direction and magnitude of the gradient is the same as the direction and speed that a rock will take when rolling freely down a hill. If the gradient vanishes, then that means that you are standing on a local flat spot such as a summit or valley and a rock will remain stationary at that spot

The harmony of colour series. Fairy glade

Stressed out at work? Are the pressures of the world getting you down? We guarantee relaxation with these complex Zen and anti-stress colouring pages for adults. The Harmony of Colour Series offers detailed images and patterns that are chosen by experts for their soothing properties. Be aware of the overall harmony of your colouring rather than focusing on each element individually. Try to balance the colors so that they are a reflection of your emotions of the moment. If the colours of your page are in harmony, then your mind will follow! Now... grab your pencils or texts and de-stress...

Classical Electrodynamics

This is a collection of my answers to problems from a graduate course in electrodynamics. These problems are mainly from the book by Jackson 3, hut appended are some practice problems. My answers are by no means guaranteed to be perfect, but I hope they will provide the reader with a guideline to understand the problems. Throughout these notes I will refer to equations and pages of Jackson and Duffin 2. The latter is a textbook in electricity and magnetism that I used as an undergraduate student. References to equations starting with a "D" are from the book by Duffin. Accordingly, equations starting with the letter "I" refer to Jackson. In general, primed variables denote vectors or components of vectors related to the distance between source and origin, Unprimed coordinates refer to the location of the point of interest.

CLASSICAL ELECTRODYNAMICS

Classical electromagnetic theory, together with classical and quan- tum mechanics, forms the core of present-day theoretical training for undergraduate and graduate physicists. A thorough grounding in these subjects is a requirement for more advanced or specialized training. Typically the undergraduate program in electricity and magnetism involves two or perhaps three semesters beyond elementary physics, with the emphasis on the fundamental laws, laboratory verification and elaboration of their consequences, circuit analysis, simple wave phenomena, and radiation. The mathematical tools utilized include vector calculus, ordinary differential equations with constant coefficients, Fourier series, and perhaps Fourier or Laplace transforms, partial differential equations, Legendre polynomials, and Bessel functions.
