| Sep 3, 2021 at 21:02 | comment | added | tobalt | Antiferromagnets even have a maximum of susceptibility at the ordering temperature. The susceptibility drops off by a power law beyond that (but never reaches zero). For ferromagnets, the high temp drop off is similar. This is all described by the Curie-Weiss-Law: en.wikipedia.org/wiki/Curie%E2%80%93Weiss_law | |
| Sep 3, 2021 at 20:56 | comment | added | D.A.S. | I disagree but, feel free to make corrections but 1) Mz = N (γ ̄h)^2*J(J+1)Bo/3kT magnetization drops to a very low level where it cannot store any more energy, L=0 at Tc. 2) superconductors have a different equation for Mz and drops the latter parts, but not relevant here anyway. 3) MRI's like torroids leak a lot of flux like magnets, which also has nothing to do with the saturation property in this question. This 7 Tesla MRI imploded the images of all the CRT's in 7 floors above when operated inside a temporary Faraday Cage. (!) R&D, The key question is saturation vs T IMHO @tobalt | |

| Sep 3, 2021 at 20:18 | comment | added | tobalt | Sorry but many things are odd (or wrong) with this post: 1) Curie temp doesn't say anythiung about permeability, infact it is not negligible at the Curie temp. 2) superconducting solenoid magnets dont have airgaps, which is the sole reason for their large stray field and tendency to attract things. Magnets with cores and air gaps are rather benign because they have large field only near the gap and cant attract things from large distance. | |
