Another mysterious artifact from the bins - and some good hints all around to what it is and how it works. Enjoy!

Another vote for the washing machine.
Can you get that thing to buzz?
Might be the kind of thing you would see on a door latch, like older apartments where you "buzz" somebody in. Perhaps the buzzer and the latch using the same AC power?
its a choke used for impedence matching
It would be much better than a simple solenoid if you wanted a more even torque over a larger range. A very clever device!!
My first thought when you showed both sides was not one of the things you mentioned.
It would be interesting to see what kind of force is exerted – maybe with a spring balance/spring scale – to give an idea of the weight of what might be moved by the arm.
My first thought was for a tuneable choke/inductor.
The lever is long enough to allow for small movements of the core into the coil. As the core moves, the flux increases and the AC is reduced.
I don’t know if such a device exists.
SOLINOID. Energized it causes a mechanical arm to move.
Love Tim's content and remember watching the TV series The Secret Life Of in the UK when I was a child.🔧👍
I love this device – where can I buy one of these?
'It's fascinating to me that such actuators and relais as well have a large pull current and a small hold current when used with AC since the magnetic circuit closes when the lever closes. That way the coil changes from low inductance, low impedance, high current and high force to high inductance, high impedance, low current and low force which is perfect for its application.
Can't have that with DC!
could you make a very silly wah pedal with that??
Variable reluctance/reactance old school
Interesting. I wonder what job it's supposed to do.
Hook a Spring with it and Make a Electric Lock…
My thoughts would be that it is an interlock that keeps the movable core pulled in while power is applied, and this whatever control it’s attached to from being moved or door from being opened. Since it has such a large range of motion, one would not expect it to pull in on its own, but stay closed when powered.
Throttle servo for a electric governor system. we put those on generator sets to replace old sluggish mechanical governers
