The problems involve rectangular or cylindrical domains that are subjected to an impressed surface current density at the boundary such that the resulting magnetic field is uniform. In one of the models the magnetic properties are nonuniform (different magnetic behavior in different regions of the model); as a result, the magnetic flux density is correspondingly nonuniform. Both linear and nonlinear material properties are used for the nonuniform case.

Material properties:

Magnetic permeability of H/m or N/A² for free space is used in the regions with linear magnetic behavior. For regions with nonlinear magnetic behavior, the response is defined in terms of a B–H curve describing the strength of the magnetic flux density as a function of the strength of the magnetic field. Table 3.5.2–1 provides the B–H curve used in these tests.
