Learning Outcomes
After taking this module students should be able to:
- apply the differential operators of vector calculus to electromagnetic problems.

- solve problems on resonance in alternating current circuits.
Brief description
This module builds on the foundations laid in PH(FG)12020, and presents the concepts of electromagnetism introduced in the earlier module in terms of vector calculus. Topics covered include electrostatics, dielectrics, magnetic fields, magnetic fields in matter, electromagnetic induction, alternating currents and resonance, Maxwell's equations.
