It' s possible?

Something like this?

Also this; can function?

My Italian/ Spanish/ whatever  is poor to non existent, but you seem to be trying to separate the nitrogen and the oxygen.

Why bother?

The air is 78% nitrogen and 21% oxygen: we can separate them electomagnetically...

with two coils, one clockwise and other anticlockwise

I dont think so you can separate oxygen  and nitrogen by an magetic field. Because the magnetic field will not have any influence on the molecules.  Magnetic field has only influence on ferromagnetic material like, iron , nickel, cobalt, gadolinium, samarium and some special alloys.

Oxygen is weakly magnetic.

You could separate them but it would take a very powerful magnet.

Why would you want to?

That's not entirely true. Magnetic field has effect on ions. Thus there is Lorentz's force:

It's used to separate isotopes with different masses and elements with different charges, in mass-spectrometry.

But here it is not the case, here it was talking about  to seperate  Oxygen from nitrogen in the air by using a magnet. Even maybe oxygen will be influenced, how big should the magnet be? Later it should get nitric acid.  This is total nonsense. Sorry to say that.

3) Electromagnetic separation. The molecules of a gas can be ionized (that is, their electrical charge can be given) if they are exposed to an electric charge. Such ionized molecules can be accelerated through another electric field and, by passing them through appropriate slots, it is possible to control the direction of movement. If this "jet" of ionized molecules passes through a magnetic field, its trajectory is bent to take a circular shape. The initial velocity imparted to the molecules is the same for all and the magnetic field exerts the same force on all the molecules. But if some of these are heavier, they will have more momentum and will be diverted less easily. Thus their trajectory will have greater radius than that of the lighter molecules, and therefore heavy molecules and light molecules will hit different targets and can be separated. This principle had already been used for many years, on laboratory scales, in the mass spectrometer.

But this is for low scale not for a commercial production of nitric acid. ,Now using also electrical fields not only magnetic ones. But it ended up by the already mentioned Birkeland-Eyde process. By using high current sparks to ionize the nitrogen to get it burned by oxygen.

The conical coil then make the reunion of N2 and O2 into NO2, at right frequency...

Build a device and try it. But I dont beleave, it will work. If it would work it would already  be invenrted.

If you want nitric acid, why would you want to separate the gases?

They need to be together to react.

Wonderfol, John

It' s all simplest

"Imbuto con bobina" is funnel with coil.

What should this device do. In the drawing the air goes through a pipe into water.  The coil is outside the funnel. What is the light blue colour, also air? 

Definitive, two stages, at few money

Hahaha, funny picture. I am wondering how looks like your high power frequency coil.
