What you will study
This module will give you a detailed understanding of the theory of electromagnetism, which is one of the cornerstones of classical physics and an example of a classical field theory. You’ll develop an understanding of a wide range of physical phenomena, from the behaviour of light to the electrical and magnetic properties of materials. In addition, you’ll develop your ability to apply advanced physics concepts and mathematical techniques (such as vector calculus) to describe aspects of the physical world and find quantitative answers to problems.
The module website will guide your learning. The website will explain the tasks you should complete in a particular week, including:
- studying written material
- completing self-assessment quizzes
- watching videos about real-world applications of electromagnetism
- carrying out online experiments.
The module is accompanied by two books. Each book chapter complements a particular week of study.
Book 1
The first book concentrates on fundamental aspects of the theory of classical electromagnetism. It explains the concepts of electric and magnetic fields and how they are related through Maxwell’s four equations (Gauss’s law, the no Monopole law, the Ampère–Maxwell law and Faraday’s law) and the Lorentz force law. It describes how the properties of electric and magnetic fields follow from the consistent theory formed by these equations and how to use these equations to understand physical situations. This book also contains brief revision material on the relevant mathematical concepts from Mathematical methods, models and modelling (MST210) / Mathematical methods (MST224). You’ll learn how to use these mathematical techniques to describe and explain electromagnetic phenomena.
Book 2
The second book starts by showing how the presence of matter modifies electric and magnetic fields and describes the tools and techniques needed to determine the behaviour of electromagnetic fields in such cases. The middle part of the book concerns electromagnetic energy and currents, particularly alternating current (ac) circuits containing electric and magnetic components. The last part of the book develops the theory of electromagnetic waves (including light) and the electromagnetic spectrum. It explains the propagation of electromagnetic waves in vacuum and their behaviour in matter, including the phenomena of reflection, refraction, dispersion and absorption.
Vocational relevance
This module will develop your problem-solving abilities in physical sciences and improve your mathematical and communication skills. The opportunity to perform a remote experiment and engage in group work is particularly relevant to how scientific investigations are increasingly carried out. These skills are useful in roles requiring a precise and quantitative approach. The learning objectives of Electromagnetism (SM381) are to develop core skills and competencies in problem-solving, communication, collaboration, numeracy and digital literacy. Personal attributes and behaviours developed will include initiative, self-management, resilience and self-confidence.
