On successful completion of this module students should be able to:
1. Discuss the concepts underpinning the physical laws in electricity and magnetism.
2. Recall, demonstrate an understanding and apply Maxwell's equations from the empirical laws of electromagnetism.
3. Explain the effects of matter on electric and magnetic fields and the boundary conditions for such fields.
4. Identify and use vector calculus and other mathematical techniques to analyse and express scenarios in electricity and magnetism.
5. Solve examples in electricity and magnetism and interpret the results in the physical context.
This module deepens the student's understanding of the empirical laws of electromagnetism. These are expressed in terms of the vector calculus notation introduced earlier in MP26020(FG26020). Problem solving skills are developed where the student is expected to identify and use relevant methods to solve broadly-defined examples in electricity and magnetism. It is a core module for physics degree schemes and provides a background in electricity and magnetism required for modules at higher levels.
The module considers the physical laws in electricity and magnetism. One part focuses on electricity and includes electrostatics and dielectrics with the other part covering magnetic fields, magnetic material and electromagnetic induction. Electromagnetic boundary conditions which apply at the interface between two simple media are discussed. The physical laws are expressed in terms of the differential operators of vector calculus and collectively presented as Maxwell's equations.
