What is the Meissner effect, which is a definitive diagnostic characteristic of a material transitioning into a superconducting state?
- 1The expulsion of a magnetic field from the interior of the material as it cools below its critical temperature✓
- 2The complete conversion of thermal phonons into high-energy photons
- 3The sudden structural rearrangement of the material's crystal lattice at absolute zero
- 4The abrupt generation of an internal electric field to assist charge carrier flow
Correct answer
The expulsion of a magnetic field from the interior of the material as it cools below its critical temperature
