An inductor is just a coil of wire around some kind of core.

How variable inductor works. When the current flowing through an inductor changes. Variable inductor products are coil products that allow the inductance to be easily varied by changing the position of the ferrite core in a threaded structure. One is a metal cylinder the otehr is an insulated cylinder and a silver plated phosphor bronze tape is wound from the insulating former to the metal former and vice versa.

It turns out however that a coil of wire can do some very interesting things because of the magnetic properties of a coil. Heres how it all works. What you see here is a battery a light bulb a coil of wire around a piece of iron yellow and a switch.

An inductor is about as simple as an electronic component can get it is simply a coil of wire. The core could be just air or it could be a magnet. When the steel bar is inserted in the tube the lamp dims from increased inductance l and consequently increased inductive reactance x l.

In a circuit diagram an inductor is shown like this. Download basic electronic components pdf a mini ebook with examples that will teach you how the basic components of electronics work. An inductor typically consists of an insulated wire wound into a coil around a core.

In this article well learn all about inductors and what theyre used for. The basics of how inductors work a demo showing an inductor filtering out high frequency signals a quick low pass lc filter and a demo showing the magnetic field created around inductors. When you apply a current through the inductor a magnetic field is created around it.

The interior is covered by a metal case that is magnetically shielded while a resin molded structure protects the windings with a high degree of reliability. Mouser offers inventory pricing datasheets for variable inductors. N4zous variable inductor design the best form of variable inductor ive seen for transmitters uses two formers.

An inductor also called a coil choke or reactor is a passive two terminal electrical component that stores energy in a magnetic field when electric current flows through it. When the tube is empty the lamp should glow brightly. Go ahead connect an inductor and capacitor and see what happens wired go ahead connect an inductor and capacitor and see what happens.

Connect this home made inductor in series with an ac power supply and lamp to form a circuit.
