Yeah, the concept of coercivity in this situation does seem out of place.
The experiment requires a B field of around 100mG (less than the Earth's), and I'm not even sure what the plan is to achieve that, considering Flux Pinning, but that is a whole other subject. We're going to turn on the...
I am modeling a magnetic coil array in Opera v15. My current project uses a CosΘ Coil inside a Metglas cylinder (Ferromagnetic) inside a Pb cylinder (Superconducting) at 4ºK. The method used to specify the a material in Opera is to specify the Coercivity and Relative Permeability.
If I had...
