Principles of Magnetics

  • John M. Eargle


In this chapter we will cover basic magnetic theory, including an overview of the steps involved in designing a typical magnet structure for a cone driver. We will also discuss aspects of materials and examine some of the fundamental nonlinearities in the magnetic and moving systems.
