Which solenoid component physically moves a mechanically operated device?

Explanation:
When current flows, the magnetic field from the coil pulls a movable ferromagnetic piece into the coil, converting magnetic energy into linear motion that operates the mechanism. That moving piece is the plunger, which translates the magnetic pull into the mechanical action. The coil itself stays stationary, and a return spring often pushes the plunger back when power is removed. So the component that physically drives the mechanically operated device is the plunger.
