Pre-Requsite: Electrodynamics-I

Objectives/Leraning Outcomes: This course is the continuation of "Electrodynamics-I". A charge creates an Electric field when it is at rest, it creates both electric as well as magnetic field when charge is in motion. Our obejctive is to study these fields and deduce some basic laws which govern all of our communication systems, and in the later part of this course we will be using these laws to discuss daily life problems such as Electricity transmission lines, TV, Radio or Mobile signals etc.

Course Outline

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.
