construction of a basic inductor?

Question

i should how to answer about this question this is about the inductor question hope someone can help me thank you

Answer 1

A basic inductor is a closely-wound coil of wire, either with an air core, or a core of a magnetic material, usually iron or ferrite.

Answer 2

Since this is an engineering board, I will give you an engineering answer.

Technically speaking:
An Inductor is any material which creates a magnetic field in an electrical circuit.
Hence the term electomagnetic.
Therefore, Any conductive material placed between opposite polarity Electric fields
creates a current, which generates a magnetic field and is a "basic" inductor.
A piece of wire between battery terminals is a "basic" inductor.
Granted, the magnetic field may be neglidgeable and can be discarded for most practical purposes,
but it is by definition a "basic" inductor.

Now, to either increase or decrease the effect of induction in a circuit is accomplished by using,
different configurations and materials; i.e. Gold vs Copper. Thick vs Thin wire. Hollow vs solid wire, square vs round wire, etc, etc.
To increase the induction effect, coils and cores are used, which is probably what you are after.
A more precise term to use is an induction coil.

Inductor:
One that inducts, especially a device that functions by or introduces inductance into a circuit.

Inductance:
1. that property of a circuit by which a change in current induces, by electromagnetic induction, an electromotive force.

Food for thought:
The effects of induction in electronic circuits is a critical aspect when designing high frequency circuits.
The wiring in a computer creates induction fields which must be compensated for.

Do a web search of the following to investigate the effects of induction at high frequencies.
impedance effect of high frequency on a conductor

P.S. Impedance is the combined Capacitive and Inductive Loading of materials.
