This benchmark combines a couple of simple well known cases to create a model with an analytic
result, yet which is challenging enough to distinguish the relative capabilities of different
simulation software for a class of real permanent magnet simulations.
Introduction

For a large fraction of permanent magnet applications,
the magnet properties characterized by a second
quadrant magnetization curve with two points:
B – the B vaue for H=0 r
H – the H value for B=0 c
This is especially appropriate for highly linear materials
such as Neodymium ceramics, but even nonlinear
materials such as Alnico normally need to be stabilized
for predictable behavior, then are used in a regime
which is reasonably linear. Hence, for a given
application effective B & H values can be selected. r c

The slope of this graph, in Gauss-Oersted units, gives
the effective permeability of the magnet.

An ideal ...
