Electromagnetism (U01356)

? Credit Points : 10 ? SCQF Level : 9 ? Acronym : PHY-3-ElMag

A course on the time-independent and time-dependent properties of electromagnetic fields in vacuo and in matter, leading to Maxwell's Equations, which encompass the laws of classical electromagnetism. These laws are used to derive properties associated with 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, adsorption, attenuation, dispersion, reflection, transmission, evanescence, and the skin effect in conductors; derive and explain total internal reflection, polarisation by reflection, and the properties of waveguides and related devices
10)Explain and utilise the properties of the magnetic vector potential, and outline its relevance to the phenomenon of radiation
