Thanks, i wonder what frecuency could be the best if 60hz, Khz or Mhz.

[naldo77]

I dare to say that the higher the frequency, the higher the induced magnetic flux and therefore more force for levitation. However, the use of a high frequency requires an extra equipment. I am afraid that such additional equipment could hide the beauty and charm of the experiment. I believe that the simpler, the better, in order to show the beauty of the "invisible" magnetic force.

Could an cheap 12V/3A AC transformer works?

[naldo77]

No way considering this coil. If you use another coil with a light weight it might work. Your should consider just a few turns and a short diameter. On the other hand, the number of turns should be enough to produce a magnetic flux that is able to levitate the coil. Good luck!

[Nonetub]

DC or AC? Specify the amperage or freq and the voltage. How many turns? What AWG number? Diameter of the coil?

The Coil gets heater? or the temperature is maintained in the coil?

Thanks

See the details on the other posts. Diameter? I dont remember exactly but according to the video image it might be between 15 and 20 centimeters. I recommend to use aluminium because of the weight but it will get hotter. We tried to connect the coil for at most 30 seconds because of the temperature. Anyway, we had it connected for more than that in some cases.

So in a few years we should have these as cars on metal highways?

Magnetic fields can cause cancer so be careful guys!

We live in world full of different types of magnetic fields i think its no good. Cell phones, wi fi, microwaves, 3g, etc

this is what we want to do with my freinds

ive allways known this was possible, but what i dont think is possible. is the fact that to power a craft/ufo sized object, you would need alot of power, but at the same time, the power soucre would have to be light weight, i dont think there is a thing on earth that could produce large amounts of power without weighting mega.

iv seen better coil but yet this guy need more time and work great work

[jaymcd84]

i wonder if the same physics of boats would work for creating some sort of vehicle that levitates over a magnetic field like a boat floats in water

[pdaniel1992]

how did you connect the coil to wire?

[rebel4evr114]

It would be interesting to see this technology used in transportation. It seems to be similar to the Maglev train but this would have more mobility.

Thanx for this video

I think it will help me bcz I am working on a project related to this subject

so here is some questions I hope u will tell me the answers:

1. the core of the coil is aluminium, doesn't it?

2. what are the metalic plate thickness and what material of metal did u use?

3. the wire u use to endure the high current, what is the cross sectional area of it?

4. If I can't get a high current source, what can I do? (maybe making the coil larger or what do u think)

Eso no es levitación, el aire se ioniza y por presion de aire sube, pero si colocamos esto en vacío no se eleva.

That is not levitation, ionized air and air pressure rises, but if we put this into vacuum don´t rises.
