The module covers in greater depth electromagnetic induction, its effects, and how it is used to advantage in electrical circuits; and the physical components, called inductors, designed to take advantage of the phenomenon of electromagnetic induction. This module is divided into four lessons: electromagnetism; inductors and flux density, inducing voltage, and inductance and induction. Each lesson consists of an overview, list of study resources, lesson narratives, programed instructional materials, and lesson summaries. (Author/BP)
