METHOD AND DEVICE FOR CHARACTERIZATION OF A MAGNETIC FIELD APPLIED TO A MAGNETIC SENSOR
摘要
The present invention provides a magnetic sensor device comprising a plurality of magnetic sensor elements having a sensitive direction. At least one of the magnetic sensor elements (43) is provided with a flux-guide (44) for concentrating onto the sensor element in its sensitive direction a magnetic field applied to the magnetic sensor device. The applied magnetic field is thus bent into the sensitive direction of the magnetic sensor element by the flux-guide. In that way, the field strength and/or orientation of the applied magnetic field can be measured in the absence of magnetic particles. This may be used for, for example, calibration of magnetic sensor devices.
