Is This How to Generate current with a constant magnetic flux?

[fritznien]

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.

so the answer is no? the magnetic field around a magnet is not uniform, the farther from the magnet the weaker it is.
put a coil of wire on top of a magnets north pole, the bottom of the coil is exposed to a stronger field then the top.
the field is still static and the voltage induced is zero. you will only see induced voltage when you have relative movement.
don't just take my word for it, try it out, its not hard or expensive to do.
