So I've been digging around the internet looking for some cool magnet desk stands, and I did find some cool stuff, levitating globes and pen holders, but that stuff requires constant energy supply.
Then I dove into quantum physics and found something called "quantum locks", basically a flying superconductor above some magnets. I thought it was cool but to get the conductor to levitate, it has to be cooled to extremely low temperatures with liquid oxygen.
Question is: are there any magnets able to float above one another without the need of constant energy supply or freezing? Any strong bowl shaped magnets I can find on the market?
