This chapter discusses the applications of magnetic forces, magnetic energy stored in components as well as magnetic circuits. The majority of the applications discussed in this section are based on Faraday's Law and the electromotive force. Faraday's Law is important in physics since it shows that a time-varying magnetic field can induce an electric field. In addition to Faraday's Law, another equation that is heavily used is Ampere's Law. This section discusses the displacement current term which was introduced by Maxwell to the Ampere's Law.
