Most solenoids will overheat if they remain energized with
the armature prevented from fully seating in the coil.

Unless the armature provides a thermal path that cannot be the case in a
DC solenoid. AC, yes -- the inductance would go up, and the current
down. DC, no -- after you get past the R/L time constant the inductance
doesn't mean anything.

Yeah, I knew that, or should have, or once did and forgot g. In any
case, any day that you learn (or relearn) something is a good one.
