At the Palais de la Decouverte in Paris, they showed me this experiment where a 1kg aluminium plate is levitated above a large coil of wire that is being supplied with 800A of alternating current at 900Hz. This is by far the best demonstration of electromagnetic induction I have ever seen.
Back in London, I visited the magnetic lab of Michael Faraday in the basement of the Royal Institution. It was here that he did his groundbreaking work on induction. People had previously observed that current in a wire causes a compass needle to deflect, but more exciting was the prospect of using a magnetic field to generate current. Faraday created his famous induction ring by winding two coils of insulated wire onto an iron ring. When he connected a battery to one coil, a small pulse of current was induced in the other. When the battery was disconnected, current was induced in the other direction. This led Faraday to the conclusion that current was induced in the second coil only when the magnetic field through it was changing.
And if they hadn't been wrapped on the same ring, Faraday may have noticed that the two coils repel each other when the current is induced due to the interaction of their magnetic fields. This is the same thing that is happening with the aluminium plate, except we're using alternating current to create a continually changing magnetic field. This induces an alternating current in the plate, producing an opposing magnetic field which levitates the disk.

He didn't mention the voltage either. If it runs 800 amps at only one volt, then that's only 800 watts which is the same power as a small microwave oven and less than half the power you can get out of the average wall socket, so it wouldn't be expensive to run. The big thick cables are needed for the high number of amps, but it doesn't necessarily mean high overall power.

Quite a lot of satellites use a similar method to orient themselves in a specific direction. They have a long arm with coils at the end. When the pass current through one of them, the resulting magnetic field interacts with that of the earth and produces a force that turns the satellite in the desired direction. en.wikipedia.org/wiki/Magnetorquer

In his accent he would pronounce it wate(r) with the t pronounced correctly and clearly. You don't usually drop the t in a word like water and make it a glottal stop in most accents, just the cockney accent and its modern variants. Lots of other accents (more middle-class ones) would turn the t into a d-like sound, like wade(r). Most people would also pronounce wire with a y sound these days, like wiye(r), his accent is somewhat archaic.

Thank you for this video! In the Museum of Science and Industry in Chicago, in the late 50s and early 60s when I was a kid, they used to have a similar device that worked the same way. It was demonstrated in the Electric Theater. That one was relatively portable (with casters) and smaller: IIRC, the size of a large hassock. The demonstrator would wheel it on stage and show the levitation of the aluminum plate. He (always "he" in those days) didn't have the light fixture, though. He never mentioned any of the electrical specs, but the machine gave off a distinct hum. He did show that if you pressed down on the plate, the humming would get louder. That showed the plate didn't get that hot in the short demo time, so spraying water on it wouldn't be dramatic (but he did mention the plate got warm). Also, the machine didn't have anything to prevent water from dripping into it. The Electric Theater was so cool! It was my favorite place. First time I saw strobe lights, UV light, and a microwave transmitter as big as a refrigerator. The last had two small plates on bars on the front (transmitting antennas, I guess), and he had an ear of popping corn on a stick that he placed between them, and the corn would pop on the ear! You could smell the fresh popcorn! Totally magic at the time! Imagine how I felt when compact microwave ovens started showing up around 1970! He also had a setup that would catch the shadow of an exploding balloon with a synchronized strobe flash on a phosphorescent screen! Now anyone can see high-speed videos of that, but at the time it was completely WOW!!!!!!!

+Alan Falleur 800 amps isn't really that bad. Since the wire is so thick and there are few turns, I doubt that the voltage is above 1 volt. So that makes 800 watts, or 6.67 amps at 120 VAC. 800 amps in your neighborhood is 96 KW.
@alanfalleur6550
@alanfalleur6550 8 жыл бұрын
EGL24Xx I'm just talking about the current this thing draws, not the power. The strength of a magnetic dipole induced in a coil is proportional to the current in the loop. This thing will drain an 8 amp hour battery in 36 seconds. Bad news for the hover boards, I think, if you need that kind of current to run it.
@EGL24Xx
@EGL24Xx 8 жыл бұрын
+Alan Falleur You're talking to an electrical engineer grad student... Yes the field strength is proportional to the current; no that isn't relevant. This coil wouldn't drain an 8 AH battery in 36 seconds for multiple reasons. First, there is no way a battery that small could provide that much short circuit current due to ESR. Also, capacity deceases the faster you drain a battery. Trying to pull 800 amps directly would reduce the battery to less than 1 AH. But again, that isn't relevant. The coils go in the ground, the board is just a low resistance piece of metal. But here's the thing, you need to talk about power. You would use a transformer to create large currents at low voltages with great ease. I've run 2000 amps through a cable loop I put through a high capacity toroidal transformer while drawing 3 amps on the primary. An 8 amp hour battery could be used in a buck supply to create low voltages with much higher current. There are a lot of things you aren't considering here...

+Adithya Venkaesh Iron is a ferromagnetic material, unlike aluminium. So, apart from gravity, there will also be an additional force of attraction on the iron plate from the electromagnet, trying to pull it down. If the levitating force isn't strong enough, the iron plate will simply get stuck to the electromagnet, just as iron nails get stuck to a permanent magnet. On the other hand, aluminium will be much easier to levitate, as we do not have to worry about any attractive force. It is only gravity, that needs to be countered.

Someone watched this and thought about hover boards... in a few years they'll be multi billionaires.

Yeah but the problem is what's the power source of the board? If it's a battery i'm sure it wont last very long. I can only see wired hoverboards being capable but they're limited to the extension wire :(. The hoverboard would be easy to make if we discovered renewable energy

SClassFinalFlash or just really good batteries, graphene and whatever. Charge in 20 minutes, use for a few hours. For a first hoverboard that sounds reasonable.

SClassFinalFlash there's actually a hoverboard built which looks just like the one in back to the future, and it's awesome, you can check it out, its HUVr board

***** I thought you only have to either charge the board and have the pavement covered with a metal sheet (i dont know how thick)

Nope. This has already been used for that type of tech. Unfortunately, the cost, danger, etc, etc, wasn't worth the effort. However, that's not to say a variation couldn't work. I have yet to see one. Surely our government's have craft that do more than levitate.

I saw this thing in an old popular science mag from the 50's. The pictures show they had a model flying saucer and even showed them cooking eggs on the hovering plate.
