What is it called?

I’m pretty sure it’s suspended by a magnetic field, just like were trying to do with our fusion reactors. Could be wrong though.

Book is the source material, though haven’t read it yet.

Sadly still magnetic force that loses strength exponentially based on distance

I could be wrong but as I understand it. You know magnetism based on positive and negative poles, now they can read and write SPIN, which is another property of electrons (that are in everything, even things nonmagnetic). If it’s true, and scales, we could use non-ferrous better materials to achieve what we do currently with ferrous materials.

Okay, it wasn’t just me.
