PROBLEM TO BE SOLVED: To provide a device for determining the influence of external magnetism.SOLUTION: A component 1 of the present device at least partly includes a ferromagnetic material, and includes a region 2 that has at least three magnetic tracks 3, 4, and 5 and can be magnetized. The mutually adjacent magnetic tracks 3, 4, and 5 are magnetized alternately in the circumferential direction. The magnetic tracks 3 and 4 are assigned to a first group 6, and the magnetic tracks 4 and 5 are assigned to a second group 7. In the region of the first group 6, first magnetic field sensors 11, 12, 13, and 14 including a redundant sensor are disposed radially to the component 1. In the region of the second group 7, second magnetic field sensors 16, 17, 18, and 19 including a redundant sensor are disposed radially to the component 1.SELECTED DRAWING: Figure 1 |
