    • 15.1: Magnetic Fields and Inductance
      Whenever electrons flow through a conductor, a magnetic field will develop around that conductor. This effect is called electromagnetism. Magnetic fields effect the alignment of electrons in an atom, and can cause physical force to develop between atoms across space just as with electric fields developing force between electrically charged particles. Like electric fields, magnetic fields can occupy completely empty space, and affect matter at a distance.

    • 15.3: Factors Affecting Inductance
      There are four basic factors of inductor construction determining the amount of inductance created. These factors all dictate inductance by affecting how much magnetic field flux will develop for a given amount of magnetic field force (current through the inductor’s wire coil):
    • 15.4: Series and Parallel Inductors
      When inductors are connected in series, the total inductance is the sum of the individual inductors’ inductances. When inductors are connected in parallel, the total inductance is less than any one of the parallel inductors’ inductances.
    • 15.5: Practical Considerations - Inductors
      Inductors, like all electrical components, have limitations which must be respected for the sake of reliability and proper circuit operation.
