1. A Hall sensor, comprising:
a first Hall element configured to detect a first component of a magnetic field in a first direction using a first sensitive area of the first Hall element;
a second Hall element configured to detect a second component of the magnetic field in a second direction using a second sensitive area of the second Hall element; and
a conductor track configured to generate a calibration magnetic field,
wherein the calibration magnetic field has a first significant component of a first measurable flux density on the first sensitive area of the first Hall element in the second direction, and
wherein the calibration magnetic field has a second significant component of a second measurable flux density on the second sensitive area of the second Hall element in the first direction.
