Posting in here and /diy/ for help
I'm trying to make a mini-maglev type thing (pic related) and so far I have levitation down pat. The only thing now is propulsion, which I have no idea how to accomplish:
>Tried doing coil-gun like design with solenoids, but that would run the cost too high, and it was really patchy when testing first 3 coils
>Tried doing a belt-drive system with magnets on the belt (think tank treads, will post pic) but magnets stick to the track, and/or flip over and attach to the levitation magnet
I want to keep this propulsion as magnet-based as possible. What does /sci/ suggest?
