On successful completion of this module students should be able to:
Show an understanding of concepts and physical laws in electricity and magnetism.
Explain the effects of matter on electric and magnetic fields and the boundary conditions for such fields.
Demonstrate an understading of Maxwells's equations from the empirical laws of electromagnetism.
Identify and use relevant vector calculus notation in solving broadly-defined examples in electricity and magnetism.
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 level.
The module considers the physical laws in electricity and magnetism. The first part focuses on electricity and includes electrostatics and dielectrics with the second 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.
