Magnetic Shields Superconductors are Expected to Shield the applied Magnetic Fields This Phenomenon is called Missner Effect. The phenomenon take place because the Superconductor creates a screening current that creates an opposite and equal mag. Field
Vortices When The applied mag. Field is large enough, > H C1, magnetic Fluxions (vortices) will spread all over the material However Material is still superconducting (Type II Only)
Large Fields When H ext is larger than H C2, superconductivity will be destroyed altogether.
So …!!! As long as the H ext is < H C1, no Flux penetration should occur. No Flux Creep is expected. Flux Avalanche is not possible.
