IBM selectric typewriters are full of them. Not sure if those are cheap and common or

does anyone on this list have a solenoid? something that can pull a pound or
two of force, from a distance of 1/4" or more, ideally. 12-24 volts would be

What ended up being the issue we were having with the steppers?
