SUMMARY
In Jackson's Section 5.10, the term "nonpermeable medium" refers to a material with magnetic permeability equal to that of free space, denoted as μ = μ₀. This indicates that the medium does not contribute any magnetization, allowing for the presence of external magnetic fields without interference. The discussion clarifies that while the medium is nonpermeable, it does not imply the absence of magnetic fields (B or H) outside the uniformly magnetized sphere.
