Learn how magnetic levitation works through the physics of superconductors and the Meissner Effect. See how this technology powers high speed maglev trains.

## Understanding How Magnetic Levitation Works Magnetic levitation looks like a magic trick, but it is actually a demonstration of how materials behave at extremely low temperatures. When you cool a superconductor, it begins to expel magnetic fields. This creates a powerful repelling force that allows a magnet to sit in midair without any physical support. Because there is no contact between the surfaces, the magnet stays locked in place while resisting gravity. In this video, we look at the specific physics behind this phenomenon: * The way superconductors push away magnetic fields to create a gap.
* Why cooling materials to extreme temperatures is necessary for this effect.
* How the lack of friction allows objects to spin for hours.
* The practical use of these principles in maglev trains that reach 300 mph. This interaction between magnets and cooled conductors is known as the Meissner Effect. By removing the friction found in traditional mechanical systems, we can achieve speeds and efficiency that were previously impossible. Understanding these forces helps explain how some of the fastest transportation systems in the world operate today.
