Some of them are:
1. Inductor temporarily stores energy in form of magnetic field. It is given by E=½LI² here L is inductance & I is current.
2. Inductor causes current to lag voltage by 90°.
3. Inductor consumes reactive power.
4. Inductor oppose current change in circuit for AC only. Fo DC it act as simple wire.
5. Inductors are used for blocking the AC while passing the DC. They are known as chokes.
6. Inductors are used to create magnetic fields in electrical machines for the purpose of energy conversion.

What happens when a inductor reaches a steady state?
An inductor looks like a piece of wire to DC. It will thus look like a resistor, and inductor properties do not apply.
How do you increase the inductance in a inductor?
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.
The resistance that an inductor poses to the flow of ac?
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.
What is the effect on Il as the load current IL increases?
As the load current ( I_L ) increases, the inductor current ( I_L ) in a circuit will also increase, assuming the inductor is connected in a circuit where it actively supports the load. This increase in current can lead to a rise in the voltage across the inductor due to its inductive properties. If the load current exceeds the inductor's rated capacity, it can lead to saturation or overheating, potentially damaging the inductor or affecting overall circuit performance. Additionally, increased load current may lead to higher losses due to increased resistance in the circuit.

Why doesnt a field coil in a DC shunt motor lead to short ciruit when it is a fact that an INDUCTOR is a short circuit to DC?
Yes, an inductor is a short circuit to dc...that's true....IF the inductor is an ideal one, that is, the inductor has no resistance but has inductance only. Anything in real world, as you know, is not ideal. An inductor is usually made of a copper wire. A copper wire has its own resistance. If an inductor coil is thin and long (i.e. many turns), it will provide an appreciable resistance to DC, and will no longer be a short circuit.
Is there no induced voltage in an inductor unless the current is changing?
In an ideal inductor, no, there is no voltage induced across an inductor unless the current in the inductor is changing. However, since there are no ideal inductors nor power supplies, eventually an inductor will draw a constant current, i.e. the limit of the power supply; and, since no inductor has zero ohms at equilibrium, that current will translate to voltage.
Why we use the inductor?
To answer these questions I will tell you which devices or equipments are inductive.These include:TransformersHair clipers,hair blowers,motorsYou hopefully know what those devices or equipments are used for,hence why we use inductors.
How do you construct an inductor?
any conductor wound with few turns can be considered as an inductor
What is working principle of inductor?
A changing current through an inductor induces a voltage into the inductor, the direction of which always opposes the change in that current.So, in a d.c. circuit, an inductor will oppose (not prevent) any rise or fall in current, although the magnitude of that current will be determined by the resistance of that inductor, not by its inductance.In an a.c. circuit, because the current is continuously changing both in magnitude and in direction, it acts to continuously oppose the current due to its inductive reactance. Inductive reactance is proportional to the inductance of the inductor and the frequency of the supply. The vector sum of the inductive reactance of the inductor and the resistance of the inductor, is termed the impedance of the inductor. Inductive reactance, resistance, and impedance are each measured in ohms.
What is the purpose of inductor?
The fundamental purpose of an inductor is to store electrical energy in a magnetic field.
When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
