Learn the fundamental concepts underlying operation of a linear motor.


Based on your laboratory experience with fabrication and operation of an electromagnetic solenoid, complete a lab report with analyses of the following:

  • Where is the electromagnetic field of the solenoid the strongest and where is it the weakest?
  • Based on this observation, what is the optimal positioning of the permanent magnet in the solenoid tube? Use this information to determine optimal lengths for armatures to position the magnet in the solenoid tube? 
  • What are the advantages of trial fitting a prototype before fabricating the final version of the frame for the linear motor? 


  1. Fabricate a solenoid by wrapping wire around a 3D printed tube.
  2. Test the solenoid
