Could hand held motor be powered from the resonance of power supply cabling behind a dry-wall ?

Nothing hardcore, but enough to get it going; as if connected to a 9V battery.

Yes and no.

 

Yes this is the principle of the magnetic impellor in a central heating pump.

No you can't get something for nothing. You would need sufficient current to be flowing in the cabling for the magnetic coupling.

I'm surprised that the forum doesn't allow for folk to see that.

The forum software does not show names when one can plus or minus a post. If there was  a like-only option, ala Facebook, then one would see the names. The mods felt showing the names of those who disapprove was not a good idea... IIRC

The software allows it. The configuration chosen here does not (for regular users, staff IINM can). This was based as SJ notes on problems with how the system behaved when such activity was visible (reciprocal in good and bad ways… retaliation, etc.)
