An inductor is an electrical component, usually a coil, designed to offer a specific value of inductance (measured in henrys). As the operating current of an inductor affects its inductance its inductance value (inductors are not linear devices, due to their hysteresis characteristics) is normally expressed for a specific range of operating currents.
Inductors can be used for a great many purposes. Terms, such as 'choke', 'reactor', etc., describe applications of inductors.
INDUCTORS are a type of passive electrical devices that are used to store energy from magnetic fields and release it when needed.The electronic component(mostly a coil) which opposes the changes in current in circuit is called an inductor . The ablitity to oppose the change of current flowing through is it is called inductance of the coil / inductor .The inductance of an inductor may also be defined as ablity to produce induced voltage when current varies through it .
To calculate the inductance of a home made inductor simply take the number of turns,the magnetic flux linkage and the current and use the inductance formula.
An inductor has two properties. The first is resistance(measured in ohms), which is due to the length, cross-sectional area, and resistivity of the conductor from which it is wound. The second is inductance (measured in henrys), which is due to the length of the inductor, its cross-sectional area, the number of turns, and the permeability of its core.The inductor's resistance limits the value of current flowing through the inductor. The inductor's inductance opposes any change in current.
Since we know that inductance of an inductor depends on the length of inductor by the formula L=muAN*N/l, where l is the length of inductor. So by varying the length of inductor we say that inductance of inductor varies.

Four (4) 0.6 Henry inductors connected in series should add up to 2.4 Henry. An electrical event passing through one inductor in time "T" will require "4T" to pass through all four inductors. Hence, inductance adds up in a series of inductors connected end to end.

what is iron core inductors
To calculate the inductance of a home made inductor simply take the number of turns,the magnetic flux linkage and the current and use the inductance formula.
An inductor resists a change in current. The equation is ... di/dt = V/L ... where di/dt is the rate of change of current in amperes per second, V is the EMF is volts, and L is the inductance in henrys. Looking at this, you can see that the slope of the current is proportional to the voltage and inversely proportional to the inductance. One characteristic of inductors is that when you have a current established, and then break the circuit, the inductor will respond by trying to maintain the current. If this is not possible, such as when the circuit is open, the inductor will generate a large reverse EMF - in the theoretical case, an infinite EMF - in the practical case, several thousand volts, depending on the inductor. This is why proper design of inductors in DC circuits, such as relays and solenoids, must include reverse EMF suppression, such as a diode or resistor across the inductor.
The resistance of an inductor is generally referred to as the series resistance, sometimes noted as RL. Note that resistance is a DC measurement and that an "ideal" textbook inductor has an RL of 0. The reactance of an inductor is an AC measurement which measures the reaction of a component's current flow to an alternating voltage and is frequency dependent and directly proportional to the inductor's inductance, measured in Henrie's. The impedance is most commonly used when talking about inductors or capacitors and is a combination of resistance and reactance.
