 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 Faradayâs law of electromagnetic induction.
apply Lenzâs law in different situations.
understand how alternating current is produced in a generator.
GUIDING QUESTIONS
âCan a magnetic field produce a current?
âHow is electric current produced?
