Learning Outcomes
After completing this paper students are expected to:
  1. Be able to recast the electric and magnetic fields in terms of scalar and vector potentials and to recast Maxwell's equations in terms of these potentials
  2. Understand the concept of an electromagnetic gauge, in particular to understand the use and importance of the Coulomb and Lorentz gauges and be able to perform simple gauge transformations
  3. Understand the conservation of energy and linear momentum in the interaction between electromagnetic fields and matter and be able to use the Poynting vector to find the energy density, linear momentum density and angular momentum density of a system of electromagnetic fields, charges and currents
  4. Understand the concept of retarded time and retarded scalar and vector potentials be able to show that these potentials satisfy the appropriate Laplace equations
  5. Understand the Lienard-Wiechert potentials as special cases of retarded potentials, understand the physical significance of these potentials and be able to use them to analyse simple configurations of charges and currents
  6. Understand the production of electromagnetic radiation by accelerating charges
  7. Be able to derive and analyse the fields radiated by oscillating electric and magnetic dipoles
