Flipping
The internal magnetization of the sensor strips has two
stable positions. So, if for any reason the sensor is
influenced by a powerful magnetic field opposing the
internal aligning field, the magnetization may flip from one
position to the other, and the strips become magnetized in
the opposite direction (from, for example, the ‘+x’ to the
‘ x’ direction). As demonstrated in Fig.6, this can lead to
drastic changes in sensor characteristics.

The field (e.g. ‘ H
magnetization, and hence the characteristic, depends on
the magnitude of the transverse field ‘H
field ‘H
since the greater the field ‘H
magnetization's rotation approaches 90 , and hence the
easier it will be to flip it into a corresponding stable position
in the ‘ x’ direction.
Looking at the curve in Fig.7 where H
such a low transverse field the sensor characteristic is
stable for all positive values of H
however, the sensor will flip even at smaller values of ‘H
(at approximately 0.5 kA/m).
