A simple design of an electric motor that uses an electromagnet and a steel rod as a piston.

***I hope to have time to make more useless but fun things like this in the future, as I have had no time whatsoever because of schoolwork.

As for the controls:
Use the mouse to drag the potentiometer (the knob all the way to the right) and spin it clockwise to increase the speed, and counterclockwise to decrease it.

The solenoid engine design is very impractical and inefficient, this is just for fun or whatever.
My design here is very flawed as I tried to make it more mechanical than just lasers and stuff.
For you tinkerers: The coil that attracts is the orange rectangle all the way to the left-hitting the left blue restraint.
