Aims

The aims of the course are to:

• Develop an understanding of electromagnetic fields and their application to the solution of a range of engineering problems, building directly on the knowledge students have gained at A-level.

Objectives

As specific objectives, by the end of the course students should be able to:

• Understand the physical properties that lead to resistance, capacitance and inductance.
• Analyse simple geometries used in these components
• Understand the basic laws of electromagnetism, Gauss, Ampere, the method of images, virtual work etc.
• Calculate the electric and magnetic fields produced by simple charge and current distributions.
• Develop an understanding of the relation between field and circuit concepts
• Calculate the capacitance, inductance, and mutual inductance for simple circuits.
• Understand how energy methods can be used to estimate electromagnetic forces.
• Design simple electromagnets and permanent magnets.

Content

The emphasis during the course will be on the physical understanding of the principles involved. Only elementary mathematical methods will be used, including basic vector concepts of superposition, dot product and cross product.

The overall course will cover three main areas through the two parts:(i) electrostatics: (ii) magnetic fields: and (iii) magnetic materials. Each part will contain a theoretical description of the concepts followed by applications to a range of problems of engineering interest. Part 1 is designed to introduce the physical properties of electromagnetics leading to the resistor, the capacitor and the inductor. This is done through a purely scalar theoretical analysis of the electromagnetic concepts. Part 2 takes the concepts of Part 1 and expands them on a more general sense to gain a more fundamental understanding of electromagnetic problems and materials. Throughout the course there will be an emphasis on the way approximations must be introduced when analysing engineering problems.
