Can someone identify this thing?

This looks like something someone who is technical and knows
radio electronics but does not know how control electronics would
be designed. Like the function of magnetic hall effect sensors.

If that added section is just ferrous metal then that ferrous
segment might conduct magnetic field from the magnets rotating
on the wheel - saturating the antenna loop, Quite-ing an
AM radio station. It would pay to look at the audio ouput
section of the radio and to see what it's connected to.
You may want to connect an earphone or speaker there and
see what you hear. Is it a varying tone or AM radio station
or 2.5Mhz WWV. maybe below 530Khz in the LF band with
it's lightning induced static. It may have been built either as
just a magnetic position sensor like a magnetic metal
detector or a remote syncronizer or speed control of
some kind.  The above high level functions are very truely
just guesses.

It looks like an AM tuner because I think FM radio would
have much smaller capacitors (1-2pf) and much smaller
hairpin like coils. It's does not look busy enough for AM/FM
radio frankly.

Ok, thank you for your quick response!

I am not shure if i put this in the right forum but i do think this i connected somehow to the TPU or Leedskalnins flywheel. My research have let me to think that Ed's flywheel works like the TPU.

As in the picture we can se that the ferrite is moved (to the right) and i think another magnet is inserted at the ferrits left end. What could this be for?

NO ! 

THE TPU WORKS LIKE RADIO ! 

THAT'S WHY IT NEEDS SPEAKER WIRE AND SOME TUNING OK 

THAT'S IT

Its from a website (older version) that is about Coral Castle.

hi 3.14, where did the photo come from?

OK thanks. Yes its definitely a transistor radio board with the ferrite antenna rod end interacting with probably a PM. I can't work out how the magnet could spin on the alu wheel without crashing into the rod. perhaps the radio was rigged to emit a tone proportional to gauss in the rod (a make shift audio gauss meter) then the rig was span up (with modified radio attached) whilst listening for a change in the tone or something, just a guess.

I beleive the flywheel was not designed to actually spinn around, the magnetic flux was.
