  • None.

Excluded Combination of Modules

  • None.

Aims

  • To appreciate classical electromagnetism, one of the fundamental physical theories.
  • To develop and exercise mathematical methods.

Content

  • Electrostatics: Coulomb's law and vector superposition of forces due to different charges.
  • Electric fields due to point charges and to volume and surface distributions.
  • Electric field E expressed in terms of electrostatic potential.
  • Differential equations for the electrostatic field.
  • Electric dipoles.
  • Dielectric media and electrostatic polarisation.
  • Perfect conductors.
  • Electrostatic energy.
  • Steady magnetics: current density j and conservation of charge, magnetic field B due to a current-carrying loop.
  • Differential equations for B.
  • Magnetic dipoles.
  • Permeable media, magnetisation.
  • Time-dependent fields and Maxwell's equations: Faraday's law.
  • Maxwell's equations with microscopic sources and in simple media.
  • Electromagnetic waves: Plane waves.
  • Polarisation.
  • Transmission and reflection at plane boundaries.
  • Special relativistic formulation of electromagnetism: Maxwell's equations with microscopic sources expressed as tensor equations in Minkowski spacetime.

Learning Outcomes

Subject-specific Knowledge:
  • By the end of the module students will: be able to solve novel and/or complex problems in Electromagnetism.
  • have a systematic and coherent understanding of theoretical mathematics in the field of Electromagnetism.
  • have acquired a coherent body of knowledge of these subjects demonstrated through one or more of the following topic areas: General features of electric and magnetic phenomena.
  • charge and current densities and charge conservation.
  • Electrostatics.
  • Time-dependent fields.
Subject-specific Skills:
  • In addition students will have specialised mathematical skills in the following areas which can be used with minimal guidance: modelling
Key Skills:

    Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

    • Lectures demonstrate what is required to be learned and the application of the theory to practical examples.
    • Assignments for self-study develop problem-solving skills and enable students to test and develop their knowledge and understanding.
    • Formatively assessed assignments provide practice in the application of logic and high level of rigour as well as feedback for the students and the lecturer on students' progress.
    • The end-of-year examination assesses the knowledge acquired and the ability to solve predictable and unpredictable problems.
