You can amp it to confirm. I think you will be surprised.
This solenoid is not meant to be modulated. It's yea or nay.
If it is a shoe pad clutch, there should be a mechanical spreader adjustment.
But I understand your thinking. Consider this.
When the plunger moves....it changes the reactance of the coil.
Plus, when you moved the plunger....you gave it inertia(made it heavier)....this will effect reactance time also.
It can get very complicated and around in circles quickly.
It would be an interesting quest. You would have to tune it, and the frequency would be slow because of the plunger.
