I found this on the beach today. There is a quarter for size reference. At first I thought it might be a rivet, but it's made of copper. And the more I look at it, I can't tell if it might even be brass. Dad thought it might be part of a solenoid (picture windings around it) from something. Pictures aren't good (phone, sorry), so I doubt anyone can see; but there is what looks like an iron rod in it with a slight gap between the wall (would suggest solenoid somewhat). I was thinking it might be a terminal post of some sorts. Any ideas? Thanks
Odd copper what's it

i've seen both brass and copper rivets, but that just doesn't look right for it to be a rivet.
as for the plunger part from a solenoid, that's a good possibility.

A sensor of some sort with the fitting end broken off...

I'll have to tear one apart, I've never seen the inside of one before!
hmm.... ...maybe some sort of thermostat. The idea of a sensor of some sort never crossed by mind. Good possibility.
