Abstract:
An apparatus includes a sensor arrangement with a sensor chip. A magnetic field generator is configured to generate a secondary magnetic field opposing an external primary magnetic field at the sensor chip. The magnetic field generator protects the sensor arrangement against the external primary magnetic field.
