Permanent magnets

[steudner@xxxxxxxxx]

Dear all,

I want to solve the problem with a metal disk rotating
in the air gap of a magnet. In a first step I want to
show the flux-density in the neighbourhood of a permanent
magnet. I added to the properties of a block the properties
of a material from the library connecting SmCo. The results
for a 25x13x3 permanent magnetized in the direction of 90
degrees to the 25x13 plane show in the 25x3 cross-section
high density only near the 3 mm sides. I think that this
is not real and connected with the model of permanent
magnets used in the program and showed in figure 31 of the
users manual. Is that right? What can I do, to obtain better
results for permanent magnets?

Regards
