Several years ago, I saw a show on one of those science channels wherein folks magnetically levitated frogs and spiders. Don't recall whether the show was "Beyond 2000" or "The Next Step".

zap.

[DannyTN]

That's interesting.

Do the materials assume magnetic properties once they are in the cold oxygen?

Practical uses other than separating metals?

[MrFred]

thats cool. now if they can do something to levitate my stock portfolio, they would really have something going.

About three years ago I saw a special on TV where they used high magnetic fields to float a strawberry and a live frog.

I wonder if the magnetic field is producing the force, or if gravity is in fact an electromagnetic property, instead of a fundamental one?

They are not NOT using materials with inherent magnetic properties.

They're using materials that are electrically conductive. Electricity and magnetism are two aspects of the same force. A varying magnetic field will induce an electric current in a conductor that in turn generates a magnetic field counter to the original, producing a repulsive force.

It's how some kinds of maglev train proposals work. Decades ago I saw cute plans for an aluminum (non magnetic) hotplate that would float a few inches above the table. Electromagnetic coils (under the table) generated the levitation force and the induced current also kept the plate hot.

The bit about cold oxygen is interesting (how many people know that oxygen -- particularly liquid oxygen -- is magnetic?), but none of this is earth shaking.

Don't let anyone tell you gold isn't going up. the only question now is how high?

I think you meant to say they are not using materials with strong* magnetic properties.

*retain significant, residual magnetism when exposed to a magnetic field.

"Here we show that this effect can be enhanced by immersing the body in cold oxygen gas, which provides a further strong and adjustable buoyancy force that allows a wide range of materials to be levitated in an open, unpressurised vessel."

I live down south, but I hear that up North, they have cold oxygen immersion fronts that cause the water to become hard & provide a strong buoyancy force that can cause human bodies to levitate on hard water in an open & unpressurised vessel!!! Has anyone ever actually seen this??

[husky ed]

I've levitated several liberals with my boots.

[Brian S]

I really miss Art Bell, the new guy just doesn't do it for my restless nights.

[UnklGene]

I've gotten old. I have something that needs to be
"re-levitated."

[error99]

I thought this had all been done years ago.

[Rippin]

FYI

[A CA Guy]

Probably would cause humans brain tumors.

[B. A. Conservative]

Greenspan is levitating gold coins with the simple of use of his computer by creating money out of thin air.
