There are some occasions when we have an air core inductor, and we don’t know what its value is. There is an easy way to obtain the inductance if you have the external measurements of this component.

The iron core inductor has very special magnetic characteristics. What they do is to reinforce the magnetic field. The magnetism of the core material depends on the bias of  “the molecular magnetic domains”

The inductor impedance. What is it? How to calculate the impedance of an inductor? The formula. The angular frequency. The “j” operator. Examples

Inductor – Coil. Inductance units. The inductor is made of a conductive wire wrapped into a spring like form. Magnetic field lines – Counter electromotive force (CEMF)

The equivalent value of a set of inductors connected in series or in parallel. These are the simplest methods for calculating the inductance of series and parallel inductors.

Inductor in direct current (DC) and alternating current (AC). Phase angle of the alternating current in an Inductor, The quality factor (Q)
