The induced voltage in the coll will go 0 V to - xyz V to 0 V to +xyz V then 0 V with the coil one way
Flipped over it will go 0 to + xyz V first then 0 & -xyz V then back to 0 again.

It definately makes a difference to coils with chips but should not make a difference to point but it only takes a few seconds to flip the coil up side down.

I got to looking closer at the magnets..
I'd you have the flywheel, outside facing down, it appears that one magnet is glued in where the longer dimension of it is horizontal along the inner edge of the flywheel , and the 2nd magnet is glued in with the longer dimension vertical along the edge of the flywheel... And they appear to not be the same height..
I'm not sure how clear that explanation was, so I'll have to snap a Photograph...

there's about 3/16" difference in the height of the two magnets. . Maybe an 1/8th.
