Pretty sure it can be done with aluminum pretty well, so it probably wouldn't be that expensive compared to some rides. You couldn't use multiple magnets on the person or they might smash together, and you'd have to be very careful guests stayed apart, and that they didn't have anything magnetic in their pockets to go flying towards the magnet and hurt them. You could do it with air pressure, like indoor skydiving in a confined area, but it would probably be loud and somewhat unpleasant. Since people aren't magnetic it would probably feel exactly the same as jumping with a harness on a cable instead of with magnets. Unless you used the frog levitation thing but that's a different effect and would probably be really expensive

The frog levitation experiment required 16 Tesla. To levitate a Human is going to require hundreds of Tesla. We're talking the kind of magnetism you'll find around stars. Expensive might not even be the right word, I think you have to dedicate a portion of society to the task of building and powering the machine that can levitate one person at a time. Realistically, we learn quickly that the machine kills people instantly.

  So it wouldn't just require the same 16 tesla acting over a larger volume?

There is no way you could put the magnets on the rider. Variance in body sizes are too enormous. You'd need them to step on to a platform that could be released. And that platform would need some engineering to prevent it from flipping. To be honest the natural end point of what you get after you engineer it for safety probably is literally just an elevator platform.

  Why would body size variation affect anything? You could just have enough magnets to slow the heaviest person enough to be safe. Although you might wind up with a hundred pound full body suit or something

    A skinny person's magnets will be less close to the walls than a fat person's magnets. Tall versus short, even just body shape will affect the rate of descent. And electromagnetism is inverse-square, which is not something you can just gloss over. And I sort of cheated by mentally running through the designs myself, like, yes, you could build a constant thing you just put people in, but, why would people want to go in the thing rather than on the thing? It is intrinsically going to be more claustrophobic in any container than being on it. So you put people on it. Then you do this, and do that, and a whole lot of safety work... and like I said, you honestly just get back to, why would anybody want this at all? Who cares if it's "really" magnets anyhow? And you just end up back at "It's a platform that descends slowly using standard elevator technology." at the end of the design process.
