Is there a wrong way to wind a multilayer coil?

I do not seem much info online just sloppy methods. Now if you wind a coil tight one direction, let's say left to right 20 times, then do you have to make the same turns from right to left 20 times? Do you go right to left 1 or at little as possible to do another 20 turn from left to right? Or it does not matter on the first or multiple layers which random pattern it goes? Obviously all going in the same direction clock wise or example.

Would it matter if it is short of long or it its for an electromagnetic induction or magnetism an object? Since it almost seems like if it was an electromagnetic induction the one side will be charged first and the charge would collide with each other to cancer it out to a degree if it is left to right and right to left in an even number. If it does not matter how come it would not negate it?

So is there a proper or improper way to wind a coil? If you need me to explain better ask.

I think there is, but I haven't tried all the variations.  Three ways that I know of:

1.  Left to right and back-n-forth until the bobbin is full.
2.  Left to right and then underneath (where the core is), then repeat until the bobbin is full.
3.  Pancake style, where you put a separating disk with a wire thickness slot and leave a narrow gap of wire thickness, then wind to fill the gap.  Once that is full, add another disk to the right and fill it.  Repeat up to the length you want.

Doug Konzen (Konehead) swears by the second method.  The third method works quite will for high voltage coils.

A really good idea would be to get three equal lengths of wire and a Gauss meter, then wind three coils with each method and test them.  This would tell the story and put the question to bed for good.  Now like everything else, there could be specific reasons why you would want to choose one method over another, but for just simple DC input and max Gauss measured at the core, it wouldn't be all that difficult to find out which works best.  If it turns out that all three coils are equally strong because of their equal length wires, that also puts the question to bed.

Regardless of what method you use to wind coils, it would be really nice to know exactly how the circular path of copper wire generates a magnetic field.  I mean EXACTLY.  Just the other day I heard a term I had never heard before: Magnon.  With that, I also heard about the Magnon's two cousins, Photon and Phonon.  To me it boils down to, "We just frickin don't know how anything really works!", so eggheads make up terms and we live with them until some new wizard comes up with different ones.  Where is Quantum (not Theory) Fact when you need it?

Well I was wondering if anyone knows an official answer and am surprised if no one knows. I assume many have tried electromagnetic induction or have tried to magnetize a nail to see the strength.

Well someone else should do it then since I don't have the proper told to conduct a test. LOL

How about this silly idea to be  left and right and at the end a wide foil around it and again to be a layer for coil, the wide insulated foil like a capacitor has it, then coil, then foil,and so on. that way its one way then all of it one way then all. that way it spins in one direction to the left then even, left, even, etc.

wire, foil, wire, foil, etc wrapped around a iron rod.
==▓==▓==▓==

I wonder how the electromagnetic current will interact with the many coils and the foil.

Also on another note can a copper nail be electromagnetic to lift iron?
