Advanced Electrodynamics

This course is extension of Electromagnetism 1. The course deals primarily with a vector analysis-based description of magnetic field, magnetic flux, and magnetic potential, and application of Gauss’s law as well as the magnetic induction for a steady current circuit. The course will cover also, the magnetic properties of the materials, and the molecular field and the classification of the magnetic materials. The course will deal with magnetic energy of the magnetic materials.
