You'd have to design them much in the same manner as a surf board. You can stand on a surf board that isn't moving without it sinking into the water (if you do it right, mind you).Danke wrote:It sounds highly likely the board will simply flip over. If the magnets are strong enough to hold a person up, I'd imagine that it would be strong enough that even a slight tilt would cause the whole thing to flip.
On the topic of magnets and distance, they also wouldn't be rare earth magnets, they'd be electro magnets, powered by some sort of fuel cell placed on the board in an unobtrusive, designed-for-balance manner. In other words, you'd be able to turn them - and the track - off. They'd also last longer.
And as shadowkhas said, many smaller magnets, or strips of electro magnets, would produce a uniform yet still strong levitation, it wouldn't be this massive outward sphere of magnetism, it would be more of a bumpy road with a whole heck of a lot of smaller spheres of magnetism, creating a rough plane on which the board levitates.

Everything you'll ever need to know about me.

i made a hover craft with a piece of play wood and a leaf blower. it worked greate to hard to steer but i could go down the street with it.

He wasn't talking about a question of balance. The magnets won't have just a negative side and just a positive side. With the bottom being one, the top will be the other. So the top will want to flip over, and become attracted to the ground.FleetAdmiralBacon wrote:You'd have to design them much in the same manner as a surf board.

That's only a affected by a lack of balance. As long as the board stays remotely level, it won't flip. This is assuming it's actually a board and not just a small sheet of magnets, which would likely flip.Leiukemia wrote:He wasn't talking about a question of balance.

You can test this on the small scale to see what I mean.

Thats what I'm going to do. I'm going to attach some magnets to the bottom of a tech deck, then lay some magnets down on a piece of cardboard, and see how it turns out.FleetAdmiralBacon wrote:That's only a affected by a lack of balance.

THEN I'll do the full scale test.

It doesn't take a strong magnet to make something float on a small scale. A much stronger magnet would be needed to lift a human person. And if you plan on trying it anyways, you should use something completely round rather then rectangular, so it's harder to flip over.FleetAdmiralBacon wrote:That's only a affected by a lack of balance.

Regardless of the shape, as long as the magnetic forces don't form a sphere, you'll be fine with the flipping part. And it doesn't take super-immense amounts of magnetic energy to lift someone weighing about 120 pounds (~54 kilos), maybe strong magnetic forces, but not ridiculously "how in God's name do you plan on doing this" strong.

Thats good, cause i weight about 110. So, I'm going to start getting magnets for this small scale test and I'll get back to you with the results.FleetAdmiralBacon wrote:Regardless of the shape, as long as the magnetic forces don't form a sphere, you'll be fine with the flipping part.

Thats what i meant, the large disc magnets for the 'actual' board and the large plate magnets for the floor.sneakyn8 wrote:if i were you i would get the disc magnets for the board and plate magnets or super magnets for the ground and the expirament about levitation for your small scale test
And for the small scale, the same thing only smaller magnets.

I'd just use electromagnets, they're a lot less expensive and can have just as much power (they lift an entire train about a few inches above a track with the right amount of power), but for a natural magnet, these would be the best choice. At the very least, the ground should be electro magnets, as you'd have to cover massive surfaces, whereas a small board can be covered in magnets like these much more easily.
Also, plate magnets would be best (if you can get them to arrange properly, you'll need some sort of extremely strong frame to keep them together)
'night.

aahahah, i was thinking about that too, but that would be even harder because of the weight distribution, i think...>_>sneakyn8 wrote:better idea put the magnets in boots and mass produce them and have a magnet rink instead of ice rinks million $ idea (be sure to give me some of the cut)
