Yeah, you would flop around a lot (the frog did), but you wouldn't be torn apart...unless it was a strong enough magnetic field to overcome the molecular bonding in your tissues!! That's really strong though, so you don't need to worry about that.

Maybe somekind of stabilizing magnets on the heavy parts of your body, so that they are repelled equally as much as the lighter parts?  It would probably cost more than it would be worth.:(  It'd still be really cool though!:D

Perhaps if you wrapped yourself in a suit made out of very diamegnetic substance...like bismuth(or however you spell that) Then you could apply a powerful magnetic field underneath you...and up you go! Much easier than relying on your own diamagneticism..

Lol, bismuth is heavier than lead and pretty rare.

but it is the most diamagnetic substance...
and it cant be that rare, they use it in shot guns now, as a replacement for lead.

Would you want to wear a suit filled with bismuth?  I don't think you'd be able to move.  Good luck with that!!:D

well if  there was a magnetic field underneath, it would be enough to cancel out gravity and then some.

and a nother question...
do you think there is the inverse of this?
A usbstance that is solid until a magnetic field hits it? then ti becomes soft or liquid until the field is removed?

If it did exist, I don't think that that substance would work on the same principle.  When the liquid becomes solid, it is because the particles align with the magnetic field and thus making the fluid more rigid.

I still like my idea of a sort of clay that would harden in an EM field.  There are so many applications...:)

Its kind of sad that we should even need that kind of technology...

E=MC2... m=deg/360 X C... C= PiD

therefore E=deg/360 X 2(PiD)

The bismuth sutit discussion was not refering to the sear tickening fluid kevlar suits already discussed in this thread but to the possibility of using a suit made out of a higly diamagnetic material, such as bismuth, to allow for the levitation of a person with a strong magnet underneath them, puerly hypothetical.

hi.... im Charls I dont know what im doing..... Ummmm i love science and im 14 years old... I thought i had an advanced accelarated knowledge about science but reading about the forums you guys were talking about, screwed my mind.... I now realize that im dumb and stupid becase i never, never understand what you guys are doing i just feel so stupid.. IM SO SO SO SORRY... I want to go to yale but i cant anymore because im stupid Yale is too advance for me i even had a B twice in P.E> leading me with a yearly GPA of 3.917 yeah i know stupid P.E. i hate my self now... Well for any advised e mail me ihatemyself_windsor92@hotmail.com

hey yalefreak92, i'm only 15.  All you have to do is read a lot and use your head, and you can understand what we're talking about.  do some searches on google for information.

Oh, and the bismuth suit wasn't even for armor purposes, but for levitation.  It would be even worse than the full body suits of armor the medieval knights wore.  I would make a very effective tank barrier though!![:p]  What if you could mount a levitation (by diamagnetic principles) device on the bottom of a car?  Could you make a hover craft?  You could use jets of air to steer/move/brake.

Could you make shelves (book/tool/what have you) that had a levitation device on the bottom shelf and amplifiers on mounted on the sides where the shelves would be?  Maybe, I'm not entirely sure how this would work, but you could then put things on shelves that "weren't there."  The magnetic fields would keep the objects from falling and it would look really cool.  What about tables or...WALLS!!  The walls could have a levitation field and would stop things from going through but it would look like there was nothing there.  You could make elevators too!!  Oh man!

It works in a different way but a superconductor is the most diamagnetic substance - it will expell all field. They have sort of levitated people using superconductors:

but it would be nowhere near as fun as being levitated like the frog.

i can do what i was hoping i can!
If you had a ring with VERY powerful magnets pointing towards the center of the ring, all the same pole (yeh theyd repel each other alot, but you can fight that) and you put that ferroliquid into it, if you had the magnets set right (slightly stronger ones on the top) you could have a wall of fluid that you could pass through, but wouldnt be visible through....i think. The very center would have influences of all the magnets (the way the feilds are shaped) and therefore you could make it so that it was equally attractive as the area closer to the magnets, if not more attractive.

This might not seem like much, but if it is a Magnetorheological fluid, which gets harder as more magnetic feild is applied, you could make a wall that could be turned on and off quite easily, or made semi permeable!
Doing more research i found there are the same type of thing, only with electrical current, and ones that are both....
I know my idea would work...
and It would be really cool....

ima design one, ill post what i design!
Thank you so much

greetings I am new to this forum. hmmmmmm Magnets... I am here to learn much about magnetic containment fields. The stronger the better, what difficulties I am experiencing is the heat disapation is going to be a hinderance. Magnetic fields are an energy that is gravity relatively speaking. It is the flow of particles, (energy) in a circular motion. the reason why magnets are not emitting heat while stagnant is because the particles are small enough that they fly through and between the molecules. There are significantly smaller particles than what we are already aware of.
The magnetic containment field will be able to compress air only because of the quantity of smaller particles outweigh that of the compressed air inside the field.
Is there anyone who can direct me to the proper information site that can help me with my search.
this will be used for new propulsion I am currently working on.
