Module Overview

This module concentrates on study of various concepts in electromagnetic induction, such as magnetic flux, induced emf and induced current in a conducting loop through the introduction to Faraday’s and Lenz’s laws. A derivation illustrating the energy transfer process and the balance of power due to electromagnetic induction is presented as well. Finally, the properties of inductors including inductance, stored energy and equivalent inductance in electric circuits are discussed in the module.

Introduction
 
The discussions in this module are heavily focused on the basic principles of Faraday’s and Lenz’s regarding electromagnetic induction. Many mathematic tools including derivative, integration, vector dot and cross products permeate the module. The right-hand rule is often referenced in the determination of induced emf and current direction which is one of the key concepts of this module. The last two units of the module are dedicated to inductors’ operating principle and properties; through inductors students can witness the linkage between electromagnetism and practical applications.
 
This module consists of a sequence of 9 videos with 2 step-by-step solved examples and 6 self-assessment questions. It is expected that the course instructor, will supplement the module with additional questions and possibly few laboratory exercises.
 
Prerequisites
 
Before starting this module, it will be helpful to be familiar with:
•    Vector dot product and cross product,
•    Integration and derivative,
•    Magnetic field and field lines.
