I just spent 5 hours of my life trying to understand this concept but i still dont get some things.
How come a sapphire has to be in the middle? what makes it special?Also, what is the super conductor material? How do you get the magnet to be permanent? I thought the object only stayed fixed if you applied pressure...
@meelmeel123 Sapphire is used in the core because it is a very poor conductor. It helps the superconductor to trap magnetic field lines significantly which means enhanced flux pinning. Their superconductor is more than likely YBCO ..or BSCCO. There are 2 ways to fix a superconductor, introducing it to the magnetic field prior to cooling or cooling while it is in the field. You do not need force to apply it externally from the field only to remove it when it is cooled within the field.
@Tolrias lol... if only there were enough tax dollars to fund this. Superconductors are stupidly expensive. Checkout mtixtl.com and see for yourself (search YBCO).
That has to be at least $4000 in material but still very interesting. I have a few questions if you don't mind. In one of your videos you show a diagram of quantum flux tubes being the reason why the superconductor undergoes quantum trapping. Is this different from flux pinning? Also where is the information from the diagram coming from? How did you determine this? Thanks. You can post in comments or shoot me a direct message.
@DwayneLeroice Thanks for your comment. The trapping is almost only due to flux pinning. The diagram is just a schematic illustration. However, we have measured the magnetic moment of the disc and found the it is negligible compared to the external field (~100 Gauss vs. ~1-8kG). We are now working on measurements of the force and its origin. Hopefully, it will be published in the coming year.
@boazal Thankyou for the response. I look forward to the published data. Also questions about the layer of gold. I'm aware that you layered the sample from high, to super to poor conductivity. I assumed this enhances the flux pinning but I wasn't too sure for the reason for the gold layer. Does it correlate to the supercurrents produced by the superconductor? as to their location on the sample? Just curious. I'm doing a bit of experimentation myself in this field.

This proves it can cerry weight, which means this can be used on more applications than I priviously thaught.

For some strange reason I think this can be applied in the future to a space elevator =D
