Ch 15: Electromagnetic Induction Overview

About This Chapter

In this overview of electromagnetic induction, you'll review self-induction, mutual induction, B-H curves, and more. You can use these brief lessons to get up to speed on the topics you might have missed in class or to prepare for a test.

Electromagnetic Induction Overview - Chapter Summary

This chapter includes a range of lessons on electromagnetic induction. These lessons cover topics like Faraday's law, Eddy currents, and hysteresis. You'll also look at how induction works between conductors and transformers. After completing the chapter, you should be able to do the following:

  • Discuss the law of electromagnetic induction and its applications in everyday life
  • Explore factors that affect the strength of electromagnetic induction
  • Describe the use of mutual induction in common devices
  • Detail how and why self induction occurs
  • Define the B-H curve and explain why it is used
  • Explain the importance of hysteresis
  • Relate the various applications or eddy currents

These brief lessons help you swiftly grasp electromagnetic induction concepts. The entertaining teaching style of our expert instructors expands your understanding of each topic covered. The video lessons offer a navigation feature that allows you to focus on specific topics, and each lesson includes a short multiple-choice quiz to test your understanding.

Faraday's Law of Electromagnetic Induction: Equation and Application

1. Faraday's Law of Electromagnetic Induction: Equation and Application

Electromagnetic induction allows us to induce voltage with the movement of a magnetic field. Credited to Michael Faraday, this discovery was not only groundbreaking at the time, but it has since led to many applications in everyday life.

Electromagnetic Induction: Definition & Variables that Affect Induction

2. Electromagnetic Induction: Definition & Variables that Affect Induction

We use electromagnetic induction every day, but do you have any idea what it is? In this lesson, we'll discuss this everyday phenomenon, the factors that affect its strength and its most common applications.

Electromagnetic Induction: Conductor to Conductor & Transformers

3. Electromagnetic Induction: Conductor to Conductor & Transformers

Every day, we make use of a special case of electromagnetic induction known as mutual induction. In this lesson, we'll talk about this special phenomenon and how it is used in many common devices.

What is Hysteresis? - Definition & Loop

4. What is Hysteresis? - Definition & Loop

Hysteresis is a common phenomenon in physical systems and occurs when the system's output depends not only on its present inputs but also on past inputs (when the system exhibits memory so to speak). Learn more in this lesson.

What is an Eddy Current? - Definition & Application

5. What is an Eddy Current? - Definition & Application

Eddy currents can heat up metal objects without even touching them, stop fast moving trains and roller coasters, and even make your workout a little more effective. Learn all about them and how they are used in this lesson!
