For sensors using Barber poles arranged at an angle of
+45 to the strip axis, the following expression for the
sensor characteristic can be derived (see Appendix 1 on
the MR effect):

The equation is linear where H/H
Likewise, for sensors using Barber poles arranged at an
angle of 45 , the equation derives to:
This is the mirror image of the characteristic in Fig.7.
Hence using a Wheatstone bridge configuration ensures
the any bridge imbalance is a linear function of the
amplitude of the external magnetic field.

As described in the body of the chapter, Fig.7 shows that
flipping is not instantaneous and it also illustrates the
hysteresis effect exhibited by the sensor. This figure and
Fig.14 also shows that the sensitivity of the sensor falls
