Abstract

See full text

A measuring system having a magnetic device for generating a magnetic field and having a magnetic field sensor for detecting a flux density of the magnetic field at least in a first spatial direction, whereby the magnetic field sensor is fixedly positioned relative to the magnetic device. The magnetic device has at least two main poles for generating a main magnetic field and at least two secondary poles for generating a secondary magnetic field. The magnetic field in the magnetic field sensor is formed by superposition of the main magnetic field and the secondary magnetic field. The magnetic field sensor is designed to measure the flux density of the superposition in the first spatial direction, and, in the magnetic field sensor, the secondary magnetic field compensates at least partially the main magnetic field in the first spatial direction.
