... crystalline structure of the material and the harder electrons will find it to flow through. Conversely, if you cool the material down, you reduce the vibrations and make it easier for electrons to flow. Superconductors are used in maglev trains, Magnetic Resonance Imaging (MRI) and Nuclear magnetic ...
