- Hello out there, here is my contribution:
-
- An ideal magnetic insulator is an ideal paramagnet (susceptibility of
- one). That means every magnetic field is pulled out of the material.
-
- Superconductors are ideal paramagnets, the phenomenia of magnetic flux
- pulled out of the material is called Meissner-Oxenfeld-effect.
-
- Hope I could help
