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.

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.

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.

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
