Harness electric currents and make them dance along magnetic threads.
Long ago, understanding electron currents allowed us to harness electricity, boosting all our technologies. But much more was yet to be discovered in the quantum world.
When the temperature is low enough, electrons can flow without resistance in a condition called superconductivity. They couple in so-called Cooper pairs, sharing a joint quantum state that lets them traverse atoms unaffected by collisions. But this is not all: magnetic fields can make them levitate, pinning them with flux strings that pass through the material and hold it in space. What new inventions can this phenomenon lead to?
What is the physics behind flux pinning?
