PHYS 1112 - Introductory Physics II
Lesson 13 - Magnetic Flux and Faraday's Law of Induction

Study Assignment:

Study: Chapter 23, Sections 23.1 - 23.5,

Read 23.6

Lesson notes:

In this lesson, we will see that a time-varying magnetic field produces an electric field.

Objectives:

1. Understand that a time varying magnetic flux can induce an electromotive force (emf), and that Faraday's law of induction is a statement of this phenomenon.

2. Be able to use Faraday's law of induction to calculate the induced emf in a wire loop or coil when the magnetic flux through the coil changes as a function of time.

3. Be able to use Lenz's law to predict the direction of the current induced in a wire loop when the magnetic flux through the loop is changed.

4. Have a qualitative understanding of how generators and motors work.

Vocabulary:

motional emf
