Introduction

Overview

This chapter discusses the basic parameters and principles of electric and magnetic circuits and the development of force and torque. Electric circuit parameters are normally covered in other basic courses, but they are briefly reviewed here in order to facilitate the understanding of magnetic circuit parameters.

Each electric circuit concept is analogous to a corresponding magnetic circuit concept. As a result, mastering the theory of electric circuits will help you grasp the more abstract concepts of magnetism. In order to understand electric machines, you first need a very thorough knowledge of both magnetism and electric circuits.
