SUMMARY

Type I superconductors exhibit unique characteristics, notably the expulsion of magnetic fields when cooled below their critical temperature. This phenomenon leads to the conclusion that the permeability (μ) of type I superconductors approaches zero in the presence of an impressed magnetic field (H), resulting in a magnetic field (B) of zero. The discussion raises questions regarding the permissivity (ε) of these materials, indicating a need for further exploration in this area.

PREREQUISITES
  • Understanding of superconductivity principles

What are the permeability and permissivity of type I superconductors?
 
Physics news on Phys.org
Type I superconductors expell magnetic fields as they pass below critical temperature.

I think this means that an impressed field H would result in a magnetic field,
[tex]B=H \mu =0[/tex] , so that mu is zero.

I don't know about the permissivity [tex]\epsilon[/tex].
