**** This course is now discontinued. Please see the new courses PHYS09050 Foundations of Electromagnetism (10 credit) or PHYS09060 Electromagnetism (20 credit) ****
A course on the time-independent and time-dependent properties of electric and magnetic fields in vacuum, leading to Maxwell's Equations, which encompass the laws of classical electromagnetism. These laws are used to derive electromagnetic waves. |

Summary of Intended Learning Outcomes
Upon successful completion of this course it is intended that a student will be able to:
1)State the integral laws of electromagnetism and state and derive Maxwell's equations for charges and currents in a vacuum
2)Define and explain charge and current densities (in bulk and on surfaces and lines), and conductivity
3)Define, and use the concepts of electric and magnetic dipoles; calculate the fields from dipoles and forces and torques on them
4)Define and explain: polarisation and magnetisation; the fields D, H, E and B; the relation between E, B and the force on a particle; polarisation charges and magnetisation currents; boundary conditions on fields at interfaces between media; Maxwell's equations in media
5)Define and explain in atomic terms: the response of linear media; relative permittivity and permeability; their relation to the electromagnetic energy density; nonlinear media such as ferromagnets
6)Formulate and solve boundary-value problems using: superposition methods; uniqueness principles; the method of images; qualitative reasoning based on field lines; the equations of Biot-Savart, Faraday, Ampere, Gauss, Laplace and Poisson
7)Formulate and solve with vector calculus problems of static and time-varying electrical and magnetic fields
8)Derive and apply the concepts of: Maxwell's displacement current; the continuity equation; self- and mutual inductance; Poynting's vector; energy flux; radiation pressure
9)Derive and explain electromagnetic radiation using plane-wave solutions of Maxwell's equations; apply these to problems of intrinsic impedance, attenuation, dispersion, reflection, transmission, evanescence, and the skin effect in conductors; derive and explain total internal reflection, polarisation by reflection.
10)Explain and utilise the properties of the electric scalar potential and the magnetic vector potential. |
