If the clamps are iron, you should retest without them in order to get an accurate result. The FRP-bars are shorted by the clamps and making a different path for the flux return. That is just my opinion.

I could be wrong though.

Howdy Jesus,
Yeah, you're right.  The clamps are iron, and providing another flux pathway.  I cut the FRP-Bars an inch long so that I can use some screws to secure them through the ends.  The C clamps are temporary, and I'll do another test once I modify the FRP-Bars, and add the mounting screws...

Another efficiency idea I am playing with is adding a mixture of fine iron filings and epoxy to fill up any gaps that I have between the core and the coil.  I would need to clean out any spaces that are filled with epoxy only, and then refill them with the iron filing and epoxy mix.  Little things like this kick the efficiency up an further increase the output power...

Edit:  Jesus, the C clamps are routing flux away from the core.  When they are removed the efficiency should get better, power should go up...

Good idea!

You should really make test to determine if it affects the output .

But i think the design is safe since the generator you built is almost identical the old phone magneto to the exception of the stator/rotor reversal . Magneto usually rotate a coil in a magnetic field the opposite is also feasible .

Rotate a magnet in a coilnetic field?  LOL!

Yeah, this is old school.  That is why I don't have big gains, like modern alternators.  What I am doing with the iron cores and basic magnets is late 19th century technology.  Tesla would have built something like this in college (1880's, maybe).  My angle is to explore the fundamentals as Tesla would have, hoping to re-experience his revelations...

I like to think that this is Electro-Punk, uh, sort of...  Like Steam-Punk, but with electrons, and not water vapor...
