Module Introduction

 

In Module 4 you will learn how the properties of electric and magnetic fields are observed in nature and applied in modern technologies. You will be asked to apply your knowledge to the following question:

  • How are magnetic fields and current-carrying conductors used to convert mechanical energy into electrical energy, and vice versa?
