Quantum Computing & Tech ⚛️ on Instagram: "Superconductors are one of the most mind-bending materials in modern physics. When cooled below a critical temperature, something extraordinary happens — they drop to zero electrical resistance and push magnetic fields away. This quantum phenomenon is called the Meissner effect. 🧲❄️ That’s why a magnet placed above a superconductor doesn’t just sit there — it levitates, locked in mid-air by perfectly stable magnetic flux lines. It looks like sci-fi wiz
