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."

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

@@withamit07 We can see the attraction/repulsion as between 2 fields (B1 the inducing one created by the coil, B2 created by the induced current in the ring) or as between 2 currents (I1 in the coil producing B1, I2 in the ring producing B2). The 2 currents attract if they have the same sense (e.g. both clockwise), as the 2 fields (think of 2 magnet oriented the same way, with the S pole of that above facing the N pole of that below). Now, the EMF (electromotive force) induced in the ring has a certain sense while I1 and B1 rise from a negative max to a positive max (during a ½ period, that is, ½ of 1/50 s). In this interval of time, I1 inverts its sense (negative for ¼ of a period, positive for the next ¼). So, if I2 were in phase with EMF (that is, reaching max and min at the same time), I1 and I2 would have opposed senses for ¼ of a period (thereby repelling each other), then the same sense for the next ¼ of a period (attracting), and so on. The average effect would be zero. But the ring is not a purely ohmic load, it's a coil (if only of 1) so it has inductance and I2 is delayed with respect to EMF (reaches max after). Hard to explain without drawings, but the result is that I1 and I2 have opposed senses (repelling) for a greater time. This imbalance gives a net repulsion. Compare this not-so-great average repulsion with the strong repulsion at 2m50 when the field is suddenly increased over a very short time (a transient)

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 think something more should have been said to answer the question posed by @withamit07: “When current increases there is repulsion but when current decreases there is attraction.

The 2 currents attract if they have the same sense (e.g. both clockwise), as the 2 fields (think of 2 magnet oriented the same way, with the S pole of that above facing the N pole of that below).

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?

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.

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.

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.
