Superconductors make trains float above their tracks
Superconductors, through the Meissner effect, expel magnetic fields, enabling frictionless maglev trains to float at incredible speeds, potentially transforming global transportation.
Imagine a train floating without touching the ground! Superconductors, materials cooled to extreme temperatures, achieve this by repelling magnetic fields completely, a phenomenon called the Meissner effect. This creates perfect diamagnetism, allowing them to hover effortlessly above magnets. This incredible property is the secret behind maglev (magnetic levitation) trains.
