Ch 16: Electromagnetic Induction

About This Chapter

Use this overview of electromagnetic induction to improve your understanding of topics like Lenz's law, R-L-C series circuits, electric motors, and more. These lessons will help you feel better prepared to take an exam or engage in a discussion on the topics covered.

Electromagnetic Induction - Chapter Summary

The lessons in this chapter provide an overview of electromagnetic induction. You'll review how moving a magnet produces electricity, and details about converting between electrical and mechanical energy. You'll also look at impedance in alternating current circuits. After completing the chapter, you should be prepared to:

  • Discuss Faraday's groundbreaking law of electromagnetic induction
  • Explain Lenz's law, magnetic flux, and motional EMF
  • Tell how electromagnetic induction is used in common devices
  • Define mutual and self-inductance
  • Identify the difference between electric motors and generators
  • Calculate AC current, AC power, and AC voltage
  • Explain the difference between DC and AC circuits
  • Communicate the purpose of R-L-C series circuits

These engaging lessons will help you get up to speed on electromagnetic induction. Vocabulary words are highlighted in bold for quick reference. A brief multiple-choice quiz is available for each lesson to test your knowledge, and the quizzes have links back to specific topics for further review. You can also print the quizzes for use as worksheets.

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.

Lenz's Law, Magnetic Flux and Motional EMF

2. Lenz's Law, Magnetic Flux and Motional EMF

Did you know that you can produce electricity by simply moving a magnet? In this lesson, learn more about electromagnetic induction and how electricity is generated.

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.

Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

4. Electric Motors & Generators: Converting Between Electrical and Mechanical Energy

Both generators and electric motors are common devices in everyday life, but how do they work and what is the difference between them? In this lesson, we'll explore both of them, which may produce different results but are actually more similar than they may seem.

Alternating Current Power Calculations

5. Alternating Current Power Calculations

After watching this lesson, you will be able to explain the difference between AC and DC circuits and calculate AC current, AC voltage and AC power using both rms values and peak values. A short quiz will follow.

Impedance in Alternating Current Circuits

6. Impedance in Alternating Current Circuits

In this lesson, you will learn about topics that include the difference between DC and AC circuits, the use of rms values, definitions of impedance and reactance, and calculations involving the reactance of capacitors and inductors.

R-L-C Series Circuits

7. R-L-C Series Circuits

After watching this lesson, you will be able to explain what an RLC series circuit is and use related equations to solve simple problems. A short quiz will follow.
