Aluminum Rings in Alternating Magnetic Field

Lenz's law - en.wikipedia.org/wiki/Lenz%27...

[@grain8314]

I'm sorry, in the very first sentence of the video, I made a typo and badly checked. The text of the video should be like this (I fixed the subtitles): "If we place a closed conductor in an alternating magnetic field, an induction current occurs in this conductor."

[@AThreeDogNight]

I know at 50 hertz but what voltage is used my friend? 15 to 300?

[@MrShahanwer]

Bro you did Best 👌💪

[@withamit07]

Hey you should add conplete explanation for the levitation. what you told is just half story of it. When current increases there is repulsion but when current decreases there is attraction. So how does the ring gets a net lift. I made this device and tilted it to 180° and it was still repelling. I don't understand why there is a net repulsion when there is both attraction and repulsion

[@kientrung1778]

More theoritically, the force which balances the gravity is actually the average magnetic force produce by the phase difference between the currents in the ring and the coil.

2:56 I think this illustrates how thrust vectoring magnetic Flux would work, but the broken circle would be the craft containing the magnetic generator, and the other ring is the ground. 4:35 there is a vortex in the middle of these 2 sphere shaped magnetic fields, that is a point of equilibrium between the 2 fields, that's xalled a Lagrange Point. Looking at the stars, they look like a geometric pattern from James Webb, after enough Lagrange points form, things start to arrange in crystal patterns, instead of spheres. In theory, if the circle in the above experiment spun fast enough, with enough g force, it could overcome the "gravity" of the generator, and push down on it, which explains how a small craft could overcome a larger planets Gravitational pull, or could possibly lead to light speed I think. If you spin fast enough you can overcome g force, and become like the mass of a large planet, just by using rotation.

I'm curious how launching the ring could be optimized by changing the frequency of the flux.

[@grain8314]

This is possible because the frequency is related to the magnetic conductivity of the core.

The closed ring with induced current having nearly 0 volts; the opposite model is a battery not connected to a load, it has volts but no current flow due to the resistance of the air or surrounding medium.

[@jamessparks7331]

I was planning to make coil gun but needs lots of current & currently i am not having enough batteries

[@TheGorf]

You won't get anything like a coil gun out of a battery. Even modern lithium ion. You want to do it with capacitors. In college, we played around with trying to build a simple two rail system. Using aluminum powder as the conductor at the back of the projectile. We delivered several thousand amps in a couple of milliseconds. And it kind of tore itself apart every time.

[@olmostgudinaf8100]

How hot did the steel core get during these experiments? The same currents that lift the rings are also induced in the core itself. Only the steel is a bit worse conductor.

[@grain8314]

Yes, my core heats up very quickly with Foucault currents because it is made entirely of steel. To reduce Foucault currents, you need to make a core as in a transformer - iron plates isolated from each other with paint or varnish.

[@CharlesBrown-xq5ug]

Would an array of smaii diameter equaiiy spaced vertical permanent magnets aligned the same way (visualize the shafts of thumbacks on the cardboard card they are ofen sold on) have a more intense near repulsion and less intense far repulsion to a smaller similar array in comparison to to a similar pair with undivided faces. The small array may float at a hight equlibrium above its large array.because of the more complex structure. Aloha Charles M Brown lll

[@deloslanc7755]

So the “Greater” meaning force or speed , if you will , that is thrust towards a closed system then what if we accelerated at a higher speed to affect the loop ? We should be able to use less powerful magnets & if the speed was tremendously increased , there would be no need for a “Magnet” at all . A simple piece of an alloy containing the ability to “know” “N & S” is all that is required .

[@burisvera8348]

Why the ring isnt changing direction. Only lifting up? I mean why its not spinning

[@grain8314]

It's hard to explain.

[@haitchteeceeeightnineeight5571]

To induce rotation of the ring as well as lift, the magnetic field would need to be rotating. This requires a more complex coil winding than shown here, or to use a ring with a more complicated arrangement of magnetic domains. A very common and simple type of electric motor is the squirrel cage induction motor. It uses a simple coil, and a complex ring to produce rotation.

[@abdel-hadikaddourn2bricola725]

Thanks

[@zofa300]

Very nice video. Could you please clarify why the Aluminum ring is elevated rather than keep going up and down? I expect it will be going up and down as you are using an alternating current so the magnetic flux keep changing directions up and down? thanks

[@michaelc.4321]

It’s basically because the induction is dependent on the rate of change of magnetic flux and with AC current, the flux is constantly changing and the induced magnetic field is necessarily opposing the applied one, thus instead of a decay, you get an overall repulsion. One way we can model this is just to say that the amount of resistance F=k*|dB/dt| where B is magnetic field strength (this skips a lot of stuff and is an oversimplification but is a decent approximation) if we assume that B is some sine wave, then F=k*|cos(f*t)| which means that it’s always forcing it up

[@alexandrudanciu7874]

Is not the magnetic flux that keep the aluminium ring up. Aluminium is diamagnetic (not repel, nor attract a magnetic) . Is the Eddie currents that form inside the aluminium ring that repel the ring from the magnetic flux, I asume.

[@Escekar]

Can you use this in real world situations?

[@duggydugg3937]

wonder if emf is efficient at taking aluminum out of trash

[@kreynolds1123]

I wonder if sea water can be pushed against. Sea water is much less conductive but there there must be some induced current and its magnetic field must push against the original changing magnetic field.

[@berner]

If your electromagnet is an iron cylinder and you insert an iron rod through the center of the cylinder, will it cause the iron rod to heat up? Also what would happen if you had that same electromagnetic cylinder and instead of putting an iron rod through the center, it was electromagnetic iron rod but instead of both cylinder and rod having the same type of current, one was an AC current and the other was DC? I find electromagnetism to be fascinating but I know very little about it outside of public school level science.

[@grain8314]

Yes, the iron rod heats up very quickly. For the same reason, iron transformers 50-60 Hz heat up. But transformers are made of insulated plates precisely for the purpose of reducing the effects of eddy currents on the core and its heating. My core is made of solid iron, so it heats up quickly, in just a couple of minutes it is hot. Yes, electromagnetism is very fascinating.

[@tonytor5346]

Try a closed toroid with vacuum inside containing a ferro-mercurial cobalt mixture (nano -particles in a colloid like suspension) suspension. Small coils individually wound around the toroid are connected intermittent manner one alter the other & powered in sequence so as to accelerate the mixture. As accelerating increases the mixture center inside the vacuum filled toroid therefore there is no friction with the walls. As the RPM Is increased, the mixture will become a plasma & a corona effect will be generated. Further acceleration will create a white glow that will expand outside the toroid proportional to the voltage increase. As the radial speed approaches near relativistic velocity, a decrease in weight of the toroid will occur. This is not due to “antigravity”, but rather by a poorly understood effect where the center of gravity is”hidden” from gravitation. Ever heard of the TR-3B? The central toroid is about 10m in diameter. What is not known by the general public, me included, is the exact proportions of cobalt, iron and barium per volume of mercury. Just for clarification, the entire volume of the toroid is not filled by the mixture. When it is activated and accelerated, it looks like a thin ring of glowing plasma centered inside the toroid. So the effect is not caused by a gyroscopic force, but rather hyper velocity of the gyrating plasma and the subatomic fields that are disrupted and redirected. The TR3-C is a significant leap forward, since using the same basic principle above described it is coupled with an Einstein-Bose condensate that forms outside the craft. How this is done is very hard to imagine, unless someone has profound knowledge of subatomic physics & different property of the different states of mater and how to transition from one to the other back and forth without enormous quantities of energy, since the craft generates whatever energy that is required… any thoughts? Can anyone with a solid physics background elaborate?

use less current. increase the no. of windings. This will increase resistance and reduce current but increase in windings tends to increase magnetic field strength. Overall affect of increasing winding will be less current and almost same magnetic field strength. The magnetic field strength will reduce a little in this method as the radius of coil changes
