This is my 2nd idea for a possible way to generate current using a constant magnetic flux. The 1st idea was to separate the turns of a coil so that the induced rotating magnetic field of each turn of the coil, would not counter-balance the rotating field of any adjacent coil turn. This new idea looks at the shape of the iron bar, that is the conduit for the magnetic flux. Has anyone tried attaching a magnet to an iron bar that either tapers down to a narrower/thinner cross-section or widens/thickens out into a wider cross-section, with a coil around it?

My thinking here is that as an iron bar becomes wider/thicker, you might expect the strength of the magnetic flux at the surface of the bar to drop due to the fact that a constant level of flux energy is now moving thru a larger area of iron, that also has a larger circumference. So if that's the case, then if you had a copper coil around the expanding section of iron bar, then the flux strength at the point of contact with the first turn of the coil would be greater than at the point of contact with the 2nd turn which is greater than at the point of contact with the 3rd turn, etc. It seems to me that this is precisely what happens when you have a increasing magnetic flux passing thru an iron bar/coil of constant thickness. For a fraction of a second, one part of the coil is in contact with iron that has a higher flux strength versus another part of the coil. Is it this imbalance of forces that imparts the current, which in turn allows the coil to generate it's own magnetic field that must in some way balance the unequal points of flux strength?

I'll be attaching a hand drawn diagram sometime in the next few days.

If there's a flaw in my theory, based on empirical evidence, then I'd like to hear it.

If someone can test my theory, I'd like to hear the results of that too. I'm putting this idea into the public domain. If it works, anyone can use it.

A perfect explanation to your theory is here:

Anyway, next time when you have an idea, first try just to find an explanation using Google or any other source like that... you will find an explanation for sure, often from a real professional source, just like the one given above.

The response so far seems to be that my proposed setup is static, with a magnetic field/flux that is constant and not collapsing. But is it really static from the point of view of the coil that's wrapped around the widening or tapering iron bar? That's really the question I'm asking. Can we manipulate the apparent flux strength by the geometry of the iron bar? I think that flux strength at any given point on the surface of a widening iron bar will shrink as the bar gets wider, effectively the same thing as a collapsing field in a bar of uniform thickness.

The question boils down to this. For any given permanent magnet, that's connected to one of two iron bars, one of which has twice the circumference of the other(ie. is thicker), will the flux strength as measured at the surface of one iron bar be the same compared to the other, thicker iron bar? I think the answer is no.
