Well google says that an AC solenoid will work on DC.


Of course! That's why they're made differently! It's a leftist plot!

The fact is, under some circumstances it will.


Neraly all actually.

Under others it won't -
without modification to the plunger seating it may stick,


Utter total ********.


with continuous coil DC, it may overheat.


Shows how little you understand electrical theory.

It would have to be a damned big inductance to affect current, and the
whole POINT about an AC solenoid is that the shorted turn pole will
effectively be zero inductance.

And of course if its a buzzer or bell., its not being fed DC. Its being
fer with AC at a fairly decent frequency. -- 10Hz or so.



End of story.


Indeed. Ineducable ****.


Yes, you are. You think that because you know a little bit more than a
layman, you know all there is to know. In fact you are just a thick poseur.

WE had 'trembler' style doorbells in my parents house in the 50s. WE got
fed up with feeding them with lantern batteries so my dad bought a
'bell transformer' that was AC, and fed them with that. They worked just
FINE.
