A research group from school of physics and astronomy, Tel-Aviv University proved that floating cars and skates are possible with the “Quantum levitation”. This effect can be achieved by super cooling a material called ‘yttrium barium copper oxide’ with liquid nitrogen, which turns it into a superconductor.
In superconducting state the material will be strongly diamagnetic. When an external magnetic field is applied it will create an opposing magnetic field, locking it in place. This is called Quantum locking. When the super cooled material is kept on the magnetic tracks, it will float without any support.
This levitation effect can be explained by “Meissner effect”, which is the expulsion of magnetic field from a super conductor during its transition to the super conductor state.
