Neither lead nor copper are what we would normally consider a "magnetic material" like iron.
That it interacts strongly with a magnetic field shows that a big change in the material, consistent with superconductivity, has occurred.
Quantum level effects are newly appearing in the macroscopic world, and that's always interesting.
- Melatonic 3y agoCould this not also have a big use case outside of superconductivity? Decellerators or accelerators for maglev trains or similar?
- marshray 3y agoOh, definintely! Most materials are diamagnetic, but only very weakly so. I think that a new room-temperature material that was so strongly diamagnetic that it could lift the weight of its own volume in lead probably would bring some interesting new applications.
