I haven't tested this theory but I don't see any reason why it wouldn't work. As we all know, current can be induced in a copper coil, that is
wrapped around an iron core, if that iron core contains a magnetic flux that is either increasing in strength or decreasing in strength. If the flux
strength is constant, no current is induced. I've always been puzzled as to why that would be and here is my solution to that mystery.
Imagine an iron rod that is horizontal, which is wrapped by a copper wire in a series of turns to create a coil. If we could see inside the iron core,
an increasing magnetic flux might appear as a wave of energy. When that wave hits the first turn of the coil, there will be a difference in flux
strength between the wire of the first turn and the wire of the 2nd turn next to it. I believe that it's that difference that induces the current.
The reason why I think this is the case, is that the current induced in the first turn generates it's own magnetic field which, because the flux at
that point is higher, will overpower the magnetic field that is generated by the wire in the adjacent turn, which is pushing against adjacent magnetic
fields and therefore current flows. When overall field strength in the core is constant, the magnetic field generated by each turn of the coil, is
exactly equal to that of every other turn of the coil and counteracts each other meaning that there is no current flow.
But supposing that the turns of the coil, were separated from each other by enough distance that their own magnetic fields would not interact? In that
case, why wouldn't a magnetic flux of constant strength, passing through the iron core, induce a current in the coil? If this theory is correct, then
one magnet, connected to an iron core, which is wrapped with a coil that has spaces between turns, should generate a constant flow of DC. I hope
someone, who is experienced with building electric devices, which I am not, will try this and post the results.
