A rectilinear motion proportional solenoid which exhibits linear output motion that is linearly proportional to the applied electrical current input. The solenoid has an adjustment mechanism which is external to the working components of the solenoid for adjusting the gain or rate of displacement of the solenoid after final assembly or while the solenoid is operating without degrading the linearity characteristics, thus allowing dynamic calibration of an operating system.
