Coil winding configurations
Hi guys!
I am just starting up my "career" as a hobby electronics tinkerer
and I am currently trying to get my head around how coils work. I know they come i and shapes an sizes, but for the moment I am working on normal single- and bifilar wound cylindrical (tube like) coils. One thing I can't seem to find any information on is how different configurations of the layers will affect operation of the coil. If i make the first layer by winding clockwise from left to right, what would the difference be between continuing the second layer from the right and winding to the left, and cutting the wire, starting a new layer from the left to the right, thus really creating several single layer coils in parallel on top of each other.
My main interest in this is making sure I get the most "bang for the buck", or watt from each passing magnet. As far as I have understood the magnet/coil power generation it is the magnet passing the coil pulling (or pushing) on the electrons in the copper wire while in range making the electrons rush to one side of the coil. Then in left-to-right, right-to-left alternating layer coils this is what I believe to be happening: When the magnet goes out of range the electrons bounce back as if attached to a spring, making the coil produce a negative spike, back EMF or what ever you want to call it. Would this effect be because of the alternating layers? An analogy to this would be a rope wound around a pulley. You pull on both ends, stretching the rope as far as you can until the rope reaches the maximum amount of stretch. When you then release the rope it contracts and returns to its normal length. That means you really don't get a lot out of the coil (rope) as opposed to pulling at only one end (multiple stacked single layer coils), doesn't it?
I may be totally off
, but I have heard some comments, and seen some writings on the net, that hint about this, but I can't find anything definitive. To repeat my goal: I want to wind a coil that delivers the maximum amount of magnetic flux-to-electricity conversion possible, and this is the one thing I have been able to derive from a few hours googling that might be the way.
Any input is greatly appreciated
, I feel I have gotten stuck on this subject 
as all I can find info about when I search, is hand winding, drill winding etc. All of which go left-to-right and back...
On a second note, I have also read something about coils wound in certain ways creating a layer of electrons between the winding layers, effectively creating a capacitor. Would this be caused by alternating the windings clockwise / counterclockwise? I would imagine that in some applications a combined capacitor and coil could have its uses. Some tin foil between layers to catch the electrons and get them out in a pulse perhaps?
Well, I'll stop rambling now, just a bit eager to learn
