Anyone remember the quantum levitation video that went viral a while back?
Well JIST ( Japn Institute of Science and Technology ) has created a video inspired by the PlayStation game Wipeout. Who knows? maybe we will see real wipeout racing in the future.
How it works:
The small wipeout racing craft you can see hovering in mid-air is coated with a special material – known as yttrium barium – which acts as a superconductor when cooled to -196 degrees Celcius.
Superconductors behave strangely when they get close to magnets. The superconductor forces out the magnetic field created by the magnets around it – this is known as the Meissner effect.
In the case of this demonstration the superconductor is so thin that some of the field is able to pass through the craft at its weakest points.
The spots where the field passes through are known as “magnetic flux tubes”. They exist at the thinnest areas of the plate and become trapped. These trapped tubes effectively lock it in place making it levitate and stay at a fixed position.
