To make a 100uH inductor, you would typically start with a core material such as ferrite or powdered iron. Then, you would wind a specific number of turns of wire around the core, calculating the number of turns based on the desired inductance value (in this case, 100uH). The formula for calculating inductance is L = (N^2 * μ * A) / l, where L is inductance, N is the number of turns, μ is the permeability of the core material, A is the cross-sectional area of the core, and l is the length of the coil. After winding the wire, you would typically encapsulate the inductor in a protective casing.

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.
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.
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.
In which place an inductor store energy in it?
Because inductor forms a coil with magnetic field around it. It acts as a relay also. Tasleem
What component limits current in a circuit?
A resistor or an inductor. The inductor limits transient current, not steady state current.

How do you make DC electric clean?
To remove fluctuations and make dc steadier, you can put an inductor in series and/or a capacitor in parallel.
What is the use of resistance in a LC circuit?
every inductor has some resistance. In circuit diagram, ideal inductor is shown in series with a resistor(value being equal to coil's resistance) to make analysis easy.

How do you construct an inductor?
any conductor wound with few turns can be considered as an inductor
Suppose no energy given to inductor and a decreasing current is applied to it. emf will be produced and energy is given by it.so i think energy is not stored in inductor. it is its own property?
How do you propose to connect a decreasing current to the inductor ? The initial current through the inductor is zero, and you want to connect it to a current which is not zero and decreasing. At the instant you make the connection, the inductor current is zero, and it must rise to the non-zero value where you want it to begin decreasing. The current in the inductor cannot change from zero to something in zero time. As it rises from zero to the initial value, guess what . . . the inductor is storing energy in its magnetic field, while producing the usual voltage equal to [ L di/dt ].
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.

When inductor is called short circuit and open circuit?
In DC inductor is short circuited .
What is the purpose of inductor?
