This chapter discusses magnetic fields.
As in the electric field, there are two measures of the same magnetic field.
The \\(H\\) field is the direct result of current flow.
The \\(B\\) field is the force of induction field that operates motors and transformers.
As in the electric field, the magnetic field is represented by field lines.
The \\(B\\) field lines are continuous and form closed curves.
The \\(H\\) field flux lines follow the \\(B\\) field lines but change intensity depending on the permeability of the material in the magnetic path.
In this chapter, the movement of electrical energy into inductors or across transformers is discussed.
This extends the ideas that both fields are need to move energy.
Both electric and magnetic fields are need in transformers action or to place energy into an inductor.
It will be shown that iron cores in transformers reduce the magnetizing current so that transformer action is practical at power frequencies.
The idea that a changing electric field creates both a displacement current and a magnetic field discussed in Chapter 1.
In this chapter, it is shown that a changing magnetic field produces both an electric field and voltages.
Both fields must be in transition before an electrical energy can be moved.
