This chapter introduces magnetic circuit terminology and forms of analysis commonly used in electrical steels applications. An appreciation of magnetic circuits, based mainly on Ampére's circuital law and Faraday's law of electromagnetic induction, is needed to understand design and operation of magnetic measurement systems and the function of magnetic materials in magnetic cores.
