Ok, things that might help:
If it's a single phase alternator:
* Check magnets alternating N/S
* A little shifted angle is to be expected, so this can lead to voltage loss.
* Match your load, it might be to heavy causing the voltage to collapse, little bit like a solar panel or current source. Put some resistors in series with the lamp to search for a maximum powerpoint. Idealy you could do this with one coil and a variable resistor for example. Then you should look at the voltage and current meter not at the brightness of the lamp.
* Wire your phases in series, but keep in mind the polarity, you can put them in series and in theory they give 0V. Winding direction need to be the same, otherwise turn around or swap cables! But you might know this already
* The biggest point, others already pointed out, is the magnetic field is not closed, and while this works for relatively flat coils and low power, your coils are really big/high, only a limited part of the coil will induce the strong magnetic field and create power, so you loose a lot of potential their, the rest of the coil more acts as resistor.
(edit: ok, forgot you put some kind of material in the coils as well, but still...)
You can experiment with a less high coil to verify/test find the optimum point. You can add an extra plate/rotor with magnets wich would greatly improve your design and close up the magnetic field.
I would search google for some kind of theory behind it or perhaps look at:
endless-sphere.com
Those guys are building motors with permanent magnets and stuff, I'm sure you can find some good reading material over there.
