Yeah, maglevs were just around the corner when I was a kid too. They even talked about induced magnetic fields being used to levitate the train repulsively vs. having magnets pulling on the underside of a steel rail. I’m glad the video explained how this effect works.
Obviously, for a maglev, you don’t need spinning magnets, just ones moving in a straight line, though I’m not sure where the propulsive force would be coming from.
