Brief Introduction:

This course provides an introduction to Electrostatics, Magnetostatics and their combination (Electromagnetism) and also electromagnetic waves. Topics include Magnetostatics in free space: B for line/surface/volume currents, Divergence/curl of B, Magnetic vector/scalar potential−A/Vm for line/surface/volume currents, Magnetostatics boundary conditions (on B, A, and H); Magnetic monopole/dipole/quadrupole etc., Magnetic dipole moment for line/surface/volume currents; Magnetostatics in matter: Magnetization M, Bound surface/volume currents, Auxiliary field H, Ampere’s law for H & M-differential/integral forms and its uses/applications, Magnetic susceptibility/permeability/relative permeability; Electrodynamics: Faraday’s law-differential and integral forms and its uses/applications, Mutual/self inductance, Magnetic energy for line/surface/volume currents, Poynting’s theorem; Maxwell’s equations in free space (static/non-static case), Maxwell’s equations in matter; Electromagnetic waves in free space, Electromagnetic waves in matter.

Learning Outcomes

Students completing this subject should be able to:

use Maxwell equations (All electromagnetic laws) in analyzing the electromagnetic field due to time varying charge and current distribution.
master the technique of deriving and evaluating formulae for the electromagnetic fields from very general charge and current distributions
attack problems in electrodynamics through, somewhat advanced level mathematics, and resolving them through the fundamental equations
solve electromagnetic problems with the help of electrodynamics potentials.
analyse the solution of these problems in the context of a range of applications.

be familiar with some elementary phenomena and concepts in quantum electrodynamics
