Problem description:

The nonlinear problem of magnetostatics - 2D permanent
magnet and steel keeper

Material properties:

The permanent magnet is made of ALNICO, coercive force is
147218 A/m, provided with demagnetization curve in
LIBRARY.DMS file.

The B-H curve for the steel is given in PERM_MAG.DMS file.

The problem is plane-parallel.
