Description
This is the second electromagnetism module taken by Physics students. It builds on
PHY2021 (Electromagnetism I) and
covers fundamental physics that students are capable of directly observing. The dielectric and
magnetic properties of solids are introduced and a range of interesting phenomena are covered including the
scattering of light the propagation of electromagnetic waves, etc., are important in a
wide variety of areas and in many key technologies. The early part of the module is primarily
a recap and a reinforcing of the difficult material treated at the end of
PHY2021.
This is a core subject for Physics programmes and is supported by Stage 3 tutorials and problems classes.
Module Aims
The module aims to develop students' understanding of Maxwell's equations
and their applications including some advanced topics. Specifically,
students will get to the point where they can handle the fundamentals of fields
due to moving charges and also to begin to explore the interaction of electromagnetic
radiation with matter.
Intended Learning Outcomes (ILOs)
A student who has passed this module should be able to:

Module Specific Skills and Knowledge:
 describe all the fundamental aspects of electromagnetism;
 explain and solve problems involving the magnetic properties of materials;
 explain and solve problems involving the dielectric properties of materials;
 explain many aspects of the interaction of electromagnetic
radiation with matter;
 calculate the effect of such interactions using
appropriate vector mathematics;
 calculate the fields of moving charges;
 solve problems requiring application of Maxwell's equations to a
variety of situations as outlined in the syllabus below;
