Application Notes
Magnetic Biasing
In many applications, GMR Magnetic Field Sensors make use of biasing magnetic fields. Biasing
magnetic fields provide either a magnetic field to sense (where one is not present) or create a pseudo
zero field. Back-biasing a sensor consists of applying a magnetic field through the sensor package
without influencing the sensor. The purpose is to create a magnetic field that the device can sense for
applications where no magnetic field is present such as ferrous material detection. The figure below
shows a permanent magnet used for this purpose. The magnet adjusted in the X direction, as shown,
achieves the maximum field in the Z direction and minimum field in the sensitive X direction.

Another means of biasing a GMR Magnetic Field Sensor is to provide a constant magnetic field in the
sensitive direction. The result is a sensor biased part way up its output curve shown in the figure
below.
