Classification: CPC G | IPC G

Claim 0:
1. A measurement arrangement, comprising:
a rotatable shaft comprising a first soft magnetic element;
a second 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,
wherein the sensor arrangement is arranged between the first soft magnetic element and the second soft magnetic element, and
wherein the second soft magnetic element is configured to cause a distortion of an interference field caused by the first soft magnetic element and which is superimposed on the magnetic field, 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.
