Enrolment:	73 students (approx)

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.
