* de Queiroz, Antonio Carlos M., " Oudin coil ".

* An Oudin coil is a disruptive discharge coil.

He developed the " Oudin coil ", which is an autotransforming resonator.

The Oudin configuration is disfavored by Tesla Coil builders as being an unnecessary distraction which provides no performance improvement while exposing operators to potentially lethal currents at its secondary terminal.

Nonetheless in 1989 Paul Marie Oudin ( 1851 – 1923 ), a French Physician and experimenter and Jacques d ' Arsonval were granted a patent for their configuration, nine years after the work of Tesla.

It was later revised and enlarged by Sirmond, Labbeus, and Casimir Oudin.

Towards the end of the run of Ivanhoe I was already preparing the Flying Dutchman with Eugène Oudin in the name part.

She also participated in doubles partnering with Melanie Oudin but the pair lost in the first round to Alexandra Dulgheru and Magdalena Rybáriková.

Petrova was defeated in the fourth round by unseeded American Melanie Oudin 1 – 6, 7 – 6 ( 2 ), 6 – 3.

At the 2010 Sony Ericsson Open, Zvonareva lost to Justine Henin, 1 – 6, 4 – 6, in the fourth round, after defeating Melanie Oudin and Sara Errani in straight sets.

She beat Melanie Oudin in straight sets, 7 – 5, 6 – 2, in the quarterfinals.

At the Mutua Madrileña Madrid Open, she lost to Venus Williams, 5 – 7, 3 – 6, in the second round, after defeating Melanie Oudin, 6 – 3, 6 – 4.

In 1887, she starred as Carlotta in Gasparone by Karl Millöcker in New York City at the Standard Theatre, together with Eugene Oudin and J. H.

The simplest form of a metal detector consists of an oscillator producing an alternating current that passes through a coil producing an alternating magnetic field.

A Hartley oscillator is essentially any configuration that uses positive feedback into two series-connected coils and a single capacitor forming a resonant LC tank circuit ( see Colpitts oscillator for the equivalent oscillator using two capacitors and one coil ).

The cathode was connected to a secondary coil on the oscillator coil and thus coupled the oscillator into the pentode mixer section, the signal being applied to grid 1 in the conventional manner.

It is sometimes called a tickler oscillator because the feedback needed to produce oscillations is provided using a tickler coil ( T in the circuit diagram ) via magnetic coupling between coil L and coil T. Assuming the coupling is weak, but sufficient to sustain oscillation, the frequency is determined primarily by the tank circuit ( L and C in the illustration ) and is approximately given by.

Other configurations of this equipment use two or more receiving coils, and the detected object modifies the inductive coupling or alters the phase angle of the voltage induced in the receiving coils relative to the oscillator coil.

The tuned circuit, consisting of the coil and capacitor, acts as a resonator, analogous to a tuning fork for sound waves.

Hansen proposed replacing the coil with a cavity resonator.

A single layer coil ( or solenoid ) that is used as a secondary or tertiary winding in a Tesla coil or magnifying transmitter is also a distributed resonator.

The MWO is a combination of a HV Tesla coil and a Split-ring resonator.

A Field-Reversed Configuration is formed in a cylindrical coil which produces an axial magnetic field.

The cooling coil is located in the furnace's outlet.

For example, in sound recording, fluctuations in air pressure ( that is to say, sound ) strike the diaphragm of a microphone which induces corresponding fluctuations in the current produced by a coil in an electromagnetic microphone, or the voltage produced by a condensor microphone.

The bulb is inserted into a coil that is generating an electromagnetic radio frequency field, resulting in a low-pressure inductively coupled discharge in the lamp.

As the current through the coil increases, the plunger is drawn further into the coil and the pointer deflects to the right.

The D ' Arsonval galvanometer is a moving coil ammeter.

A moving coil meter indicates the average of any varying current through it, which is zero for AC.

However, since piston-engined aircraft rely upon magnetos to provide spark to their cylinders rather than a battery powered ignition coil system, this theory is not strongly convincing.

The plates are forced together by a set of coil springs or a diaphragm spring plate when the clutch is engaged.

Traditionally, liquid helium is used to cool the coils because it has a boiling point of around 4 K at ambient pressure, and cheap metallic superconductors can be used for the coil wiring.

A coil is a series of loops.

A coiled coil is a structure in which the coil itself is in turn also looping.

An electromagnetic coil ( or simply a " coil ") is formed when a conductor ( usually an insulated solid copper wire ) is wound around a core or form to create an inductor or electromagnet.

One loop of wire is usually referred to as a turn, and a coil consists of one or more turns.

A completed coil assembly with taps is often called a winding.
