The following chart shows the output of an AA-Series sensor when it is exposed to a saturating
unipolar field:
In the case of a unipolar field, the sensor is operating on the minor hysteresis loop. The hysteresis in
this case is relatively small.
The following chart shows the output of the same sensor when it is exposed to a saturating bipolar
field:
In this case the sensor is operating on the major hysteresis loop, so the hysteresis shown by the output
characteristic of the sensor is relatively large. This is the worst-case hysteresis exhibited by the sensor
element.
