The applications of inductors are varied with each type of inductor. Some major applications include filters, sensors, Transformers, motors, and energy storage.
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.
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.
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.
Because inductor forms a coil with magnetic field around it. It acts as a relay also. Tasleem
A resistor or an inductor. The inductor limits transient current, not steady state current.
The fundamental purpose of an inductor is to store electrical energy in a magnetic field.
what is an inductor used for
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.

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.

any conductor wound with few turns can be considered as an inductor
An inductor looks like a piece of wire to DC. It will thus look like a resistor, and inductor properties do not apply.
