density in the gap varied from 0 T (at the wall of the Nd
Fe
B magnet) to
-
-
approximately 1.1 T at a distance of 48 mm from the wall of the Nd
Fe
B magnet,
-

with a maximum midpoint magnetic
fl
ux density of 1.5 T. The mass of the
Nd
B magnet (without iron) was reported to be 7.2 kg. In the experimental
device, the magnet assembly was moved over two static AMR beds, by means of
mechanical subsystem, composed of a step motor and a ball screw [
38
]. A very
similar magnet assembly was shown in a patent of Zimm et al. [
39
].
Another example is shown in Fig.
3.30
b. In this particular case we show half of
the magnet assembly that was used to provide a magnetic
Fe

ux density of 0.9 T in
the rotating disc containing magnetocaloric material. More information about this
particular device can be found in the Chap.

in the reference to the work of
Bohigas et al. [

].
