The magnet assembly (h) in Fig. 3.42 is different to all other 7 structures.
Namely, it comprises four rotating magnet poles, three of which are used to con-
centrate the magnetic ux into the fourth one. It also comprised eight AMR beds,

which are attached to the smooth static iron ring.
According to Bouchekara et al. [ 56 ], the reference magnet assembly (a) was also
chosen because of its simple construction and it was optimized in order to provide
the maximum magnetic
