Abstract
Methods and apparatuses are provided, in which a magnetic field is measured using a coil in a first operating mode and a magnetic field is generated using the coil in a second operating mode in order to test a further magnetic field sensor.
Claims21
An apparatus comprising:
- a first coil;
- and
- a first further magnetic field sensor,
- wherein the apparatus is configured to measure a magnetic field in a first operating mode using the first coil and to generate a magnetic field for testing the first further magnetic field sensor in a second operating mode using the first coil,
- wherein a current is supplied to the first coil in the second operating mode to generate the magnetic field for testing the further magnetic field sensor, and
- wherein the current is not supplied to the first coil in the first operating mode for measuring the magnetic field.
