how well would this work?

I think that's a fan with magnets on the blade, spinning alongside other magnets?

It won't do much, because to generate electricity, you need to move the magnet(s) inside coiled wire. Replace the outer magnets with wire, and the best you could do is break even, assuming a frictionless environment with no resistance to rotation from the magnetic field (try one of those generator bikes the next time you're at a science museum; the more demand you place on it, the harder it is to pedal) and perfect efficiency of generation, the best you can do is break even.

but spinning wise? like, how long couldit go? how fast?

Rig up an apparatus and test it experimentally. Keep us posted; we'll be riveted to /sci/ for you to publish your results.

It sort of seems like it would be incredibly efficient.

Im just going too assume that once you hook up a generator the friction makes the energy gained by magnets negligible.

it would find equilibrium and stall very quickly
