It is noted that the optimality criterion does not include friction because
it is not the function of geometry. The chosen design parameters to be
optimized are the effective length of the disk except the magnetic coil
(d), width of disk ux guide except the coil (G
w
) and area of the coil (C
a
).
The signicant geometric parameters are depicted on the cross-section
view shown in Figure9.2. In the gure, the light gray area is the MR uid,
the white area is the paramagnetic rod, the dark gray area is the ferro-
magnetic structures including ...
