Description of  Inductance, Energy and Power in Circuits, Coupled Circuits and Transformers

With this book I intend to introduce the reader to the interactions between magnetic and electric circuits at a circuit level. To do this we will explore in concepts of magnetic circuits and how they can be seen as equivalent electric circuits. Following on from the basics of magnetic circuit behaviour, we will examine the principles behind calculating energy flow in electric networks, and how this interacts with power flow, examining power factor of circuits and how this can be corrected. Once the basics have been explored, we will look at the behaviour of closely coupled magnetic circuits, where the magnetic fields are used to couple electric circuits together, culminating in the ideas behind simple transformer operation.
