Magnetic levitation?

The Merkaba Machine is now operating at higher speeds, with one of the slip rings replaced by a stack of Teflon washers. This modification seems to enable the core to reach rotational velocities that may be inducing a form of levitation. Furthermore, the 4-coil series-wound tank circuit plays a critical role in stabilizing this effect. Powered by the energy induced from the spinning magnet, the tank circuit acts as a resonant system that helps regulate and sustain the electromagnetic field generated by the core. This resonance may contribute to both the levitation and stability by creating a balanced electromagnetic force, counteracting gravitational pull and reducing wobble or instability during rotation.
In addition, the integration of air vents in the upper and lower sections of the central containment unit improves airflow, allowing for efficient heat dissipation. This prevents overheating of critical components, ensuring smoother operation at higher speeds. The combination of enhanced cooling and electromagnetic regulation likely boosts the overall performance and contributes to the levitation effect by maintaining an optimal thermal and electromagnetic environment for the spinning magnet.

So the noise is there on the startup but not the slow down. The other rings were not making such a sound. The heat might be expanding the part you put in. When it reaches the right level it expands and stops spinning with the magnet. It would be interesting to see the wear pattern on the part and check for any sign it heated up. Did you glue the part in? Definitely interesting.

I don't believe this is levitation at all.
I think at best you've created magnetic locking the same as most rodin coil type stuff people have done by mimicking the 1500hz (approx) harmonics as a reaction of what sounds like numerous coils multiple waves converging. 4?
But i'd be curious to see you get a camera in there and know for sure.
