This quantum levitation experiment looks like something straight out of science fiction. Magnetic Games cools a special YBCO material to an incredible -196°C using liquid nitrogen, transforming it into a superconductor with some remarkable magnetic behavior.
Once the superconductor interacts with powerful magnets, it can appear to float in mid-air and move along a magnetic track in ways that almost seem to defy gravity.
Quantum Levitation at an Incredible -196°C
The key to the demonstration is YBCO, a ceramic material that can become superconducting when cooled below its critical temperature.
Magnetic Games uses liquid nitrogen to bring the material down to around -196°C before placing it in carefully arranged magnetic fields.
The resulting quantum levitation is mesmerizing. The superconductor can remain suspended relative to the magnetic field and glide smoothly along a track with remarkably little resistance.
The effect is associated with superconductivity and magnetic flux pinning, which can hold a type-II superconductor in a stable position relative to a magnetic field.
Why We Loved This Video
Some science experiments become much more memorable when you can actually see the physics happening, and this is a perfect example.
Watching an object hover and glide above magnets looks like a clever illusion, yet the effect comes from genuine superconducting physics.
It’s visually fascinating, scientifically interesting and exactly the kind of experiment that makes you want to understand how it works.
