What is Quantum Levitation? Quantum levitation or quantum locking is the ability of a superconductor to perfectly match the magnetic fields surrounding it. AKA Quantum Locking Magnetic Levitation Magnetic Locking Magnetic Flux Locking Quantum Magnetism
What is a Superconductor? A superconductor is a material, that when cooled to a temperature below its critical temperature, it’s electrical resistivity goes to zero. First discovered by: Heike Kamerlingh Onnes
What is a Superconductor Made Of? Almost any material, if cooled enough, can be made into a superconductor. Even many materials which are insulators at room temperature can be superconductors when cooled to extremely low temperatures.
Elements : Al, Sn, Hg, Pb Alloys : Mercury or Yttrium based Organics : Carbon nanotubes Ceramics : LBCO, YBCO, TBCCO
Ceramics : Compound Critical Temp(K)
What Does Quantum Levitation Do? Because of the zero resistance properties of superconductors we get an effect known as quantum levitation. This phenomenon creates a magnetic locking effect between the superconductor and the magnetic field. Thus allowing the superconductor to levitate.
Why It Happens -The Meissner Effect: When a superconductor reaches its critical temperature all magnetic fields applied to it are excluded from the interior. In other words, the field will go around it, not through it.
-Supercurrents When a superconductor at its critical temperature is exposed to a magnetic field currents are induced within it. These currents then induce an opposing magnetic field. Due to the lack of any resistivity, the currents are able to perfectly mirror the magnetic field applied to the superconductor. The currents also adjust instantaneously with any changes in the field from things such as movement. Thus a floating piece of superconductor will stay in any position it is left in and will follow a magnetic track.
The Meissner Effect can also be explained mathematically with the London Equations.
The Future If a superconductor with a easily achievable critical temperature (ideally above room temperature) were to be found or if a system that could easily keep a superconductor at its critical temperature were to be invented…
It Is Possible!
