Magnet and Ball Bearing Demonstration

Submitted by: fancylad 8 years ago Science

Scientists invent a machine that control tiny ball bearings in a powerful magnetic field precisely to draw 3D images.

If you don`t believe what `m saying, here is the information form a listing on a video website named VideoSift:

"From BMW Museum in Munich. The kinetic sculpture consists of 714 ball bearings held up by string and moves to create some pretty cool 3D images."

there...point proved.

Wow. Whoever thinks this is magnetic propulsion is probably suffering from Necrotizing fasciitis of the brain...(not a true medical condition). This is a kinetic sculpture, not a scientific demonstration. If you cant see due to eye problems, there are strings attached to the ALUMINUM balls and there are motors in the ceiling lifting and lowering these balls in a coordinated manner in order to create the ornate figures. If there were such a thing as a magnetic field that can stay in a perfect vertical cylinder without affecting the space around it then we would already be flying to work and every thing involving magnetic fields would be so much more advanced. A magnetic field tries to connect to other magnetic fields around it creating one large magnetic field, therefore if this sculpture was created with magnetic platforms and iron/steel/cobalt/nickel/ some other magnetic alloy, they would me moving in one large glob.

Are those ball-bearings made of a nonconductor that is still hard-magnetic? I also don`t think that magnetic flux lines could be lined up so perfectly and -not- interfere with one another. The calculations terrify me. PLUS, if you were using the right-hand rule at all, then you`d know that setting up a field parallel to the plane of force does nothing - it has to be perpendicular. Plus, the separation of charges in the ball would cause potential voltage, which would create current, which would create a magnetic field of it`s own, and according to Lenz` Law, the ball would just kind of hover there and not move. That is, if everything else was right in the first place.

I think it`s just fishing line.

i was there for that and there is a magnetic platform on the ground and roof so the ball bearings can be pushed (repeled) or pulled (attracted)

thanx guys

Dan,I didn`t even think of that.
And they couldn`t be magnets,either,because they would attach to each other.

well that was fake. Can`t repel a ball bearing, end of.

Man that ruined the video. But i see your logic =(

FFS, it`s not magnets, it`s strings. The world is full of incredibly stupid people who know nothing about magnets, but are arrogant enough to assume they do.

I actually saw this exibit. It`s just balls on strings. Don`t know what the big deal. Has nothing to do with magnets.

They are actually strings; none of them loop over the others, it`s simply a good optical illusion. They`re rows of metal balls on strings controlled by electric motors connected to a computer that controls their movement. Ingenious.

This wasn`t string or magnets, strings would have tangled with each other when the top ones looped under the bottom ones, and magnetic fields wouldn`t be focusable enough to control one ball bearing. It was obviously done with telekinesis.

awhhh.
I was all excited about magnets....

Btw, those are just balls. Ball bearings are the things in rollerblade wheels, two rings with balls in between to allow them to spin independently from each other.
As in, they bear balls. Ball bearings.
Those were just metal spheres.

Yea this was on Gizmodo like 6 months ago. They had the entire story there. It`s metal bearings hung from thin wire. Definitely not magnets. We`re advanced, yes. But not quite that advanced.

I won`t be impressed unless they start playing some catchy chip-tune, with a text scroller.

lol @ superjesus telling FANCYLAD not to post fake description for more views. check the poster next time stupido.

"Yeah, it`s strings. Don`t make up sh*t to get your link more views."

Hey! This is totally possible with magnets so long as each ball bearing has a different charge. So you`ll have positive. negative, formative, knurlitive, squiblative, zambangdoozelative...

you could (theroeticlly) do this with superconducting magnets but it would take WAY too much energy b/c you have to keep it cool(verry cool)
the strings is more energy efficient.

Reading the most recent comments I take it people realize this isn`t something made by scientists, that it`s known as a kinetic sculpture, and that it uses strings.

Might I also add that i find it annoying when people post things with inaccurate or deceptive descriptions.

yeah, this doesn`t have anything to do with magnets, this was a display at BMW, and they are all on strings.

kinda cool though, nonetheless.

Unless I`m mistaken, these are on strings, and are a display at either BMW, or Mercedes Benz. (I forget which), but it`s not magnets. Cool just the same tho.
