What is superconductivity? In this video, we explain superconductivity in simple words — from the toy train analogy (a train that never stops once you push it) to how certain materials lose ALL electrical resistance when cooled below a critical temperature. Learn how Kamerlingh Onnes discovered superconductivity in mercury in 1911, how the BCS theory explained Cooper pairs using quantum mechanics, and why superconductors power MRI machines, maglev trains, and the Large Hadron Collider.
Whether you're a physics student preparing for an exam, curious about how trains can float on magnets, or fascinated by materials that conduct electricity forever, this beginner-friendly animated explainer covers it all.
