Chapter 20

Electromagnetic induction

LEARNING OBJECTIVES

In this chapter you will learn how to:

identify situations where flux changes and an emf is induced.

distinguish between magnetic flux and magnetic flux linkage.

solve problems using Faraday’s law of electromagnetic induction.

apply Lenz’s law in different situations.

understand how alternating current is produced in a generator.

GUIDING questions

●Can a magnetic field produce a current?

●How is electric current produced?
