     There is a nice video   
      
   "Animation vs. Physics" (2023) - Alan Becker   
      
     where near minute seven, coils placed in space are used to accelerate   
     a space ship. While this might not work in reality, it's still nice   
     to watch that whole video from start to end (16 minutes).   
      
     I just see there's another video "Animation vs. Math" I have not   
     watched yet . . .   
      
     PS: A web page explains that the idea was that "the south pole of   
     Orange's ship is facing the north pole of the first magnetic ring"   
     and so the ship is accelerated towards the ring. However, the video   
     ignores that when leaving the ring, the ship is still attracted to   
     the ring, and therefore it would then be accelerated backwards . . .
