[@vink6163]

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.

Had a trip to Paris this week to meet a friend, took some time apart to go to this place 'Palais de la Decouvet', saw all the electromagnetism demonstrations they do, not only this one, and many other interesting experiments in other areas of physics. The whole experience was amazing. Wouldn't have known about this place if it wasn't for you. I sincerely thank you for that.

Am I wrong about this essentially having the power to fuel a rocket? The earth gives off a magnetic field, if that field can be used as both an electrical current (Tesla!!) and a magnetic field then what keeps it from happening?

[@NischalKK]

+josiah meade changing magnetic field induces electric field. Changing electric field induces magnetic field. From our perspective, magnetic field from earth isn't changing.

[@Electroblud]

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

I was a Hull Technician in the Canadian Navy, serving on a Destroyer. I switched on our welder, and the cable was mounted on the steel wall, coiled up. As I passed this cable, all the tools shot out of my belt and stuck to the wall inside the coil. I learned an interesting lesson about magnetic fields.

[@JimC]

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!!!!!!!

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.

It’s a really fun place to visit and the people doing these demonstrations for the public everyday will be able to answer your questions. Don’t forget to come back and tell us. I used to live nearby but moved so a visit is not planned currently. Also make sure you also visit the cité des sciences et de l’industrie.

[@alanfalleur6550]

Damn, did you say 800 amps? That's like the total electric current running through all the houses in my neighborhood. Good luck to the prospective hoverboard builders who think they can co-opt this technology into practical transportation.

[@EGL24Xx]

+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]

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]

+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...

[@AlbertGuilmont]

Only one problem with this barbecue, though: where do I find 800A?

[@t0nito]

You would need a transformer, If you have a 40A 220V supply you can use a transformer to make 12V 800 A, you would need a very heavy gauge wire though. The tougher part is to convert the 50/60Hz to 900Hz

[@craniusfawkes]

For the frequency, you would need frequency dividers xD But the bigest problem would be the energy bill, I guess xD

[@FathinLuqmanTantowi]

[@adithyavenkaesh3496]

i have doubt what happens when we use a iron plate instead of aluminium ???? pls some one answer this question

[@DidntKnowWhatToPut1]

+Adithya Venkaesh My guess it would be too heavy.

[@Juxtaroberto]

+Adithya Venkaesh Same thing would happen. The magnetic field would induce a current in the iron plate, which itself induces an opposing magnetic field to the external magnetic field, and thus the plate will levitate.

[@DidntKnowWhatToPut1]

Juxtaroberto I really doubt it would levitate though. An iorn plate that big would weigh an awful lot. Needs testing

[@aditya_s95]

+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.

[@Andytlp]

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

2 major problems: 1) Heat. Any metal objects in the EM field would heat up. A field strong enough to levitate a car would heat metal up quite a bit. Anyone with metal-framed glasses would get some nasty burns on their face, for example. Not to mention, the car itself would get extremely hot. Odds are, it would cook anyone inside. 2) Any sensitive electronics (smartphones, for example) would likely be fried the second they enter that field.
