Claim 22:
23. A measurement arrangement, comprising:
a rotatable shaft comprising a first soft magnetic element;
a magnetic element that is mechanically coupled to the rotatable shaft and is configured to produce a magnetic field; and
a sensor arrangement configured to capture the magnetic field,
wherein the sensor arrangement is arranged in such a manner that a relative movement between the first soft magnetic element and the sensor arrangement results in a change in the magnetic field at a location of the sensor arrangement,
wherein the sensor arrangement is configured to determine the change in the magnetic field, and
wherein a second soft magnetic element is configured to cause a distortion of an interference field caused by the first soft magnetic element,
wherein the distortion caused by the second soft magnetic element is opposite a distortion of the interference field that is caused by the first soft magnetic element.
