Method for magnetizing permanently magnetizable element assigned to magnetic field sensor structure, involves producing test magnetic field, which penetrates magnetic field sensor structure and permanently magnetizable element

摘要

The method involves producing a test magnetic field (10), which penetrates the magnetic field sensor structure and the permanently magnetizable element. The test magnetic field is detected by the magnetic field sensor structure and a test signal is provided (12) based on the test magnetic field. Independent claims are also included for the following: (1) a device for magnetizing a permanently magnetizable element assigned to a magnetic field sensor structure (2) a safety device for a sensor arrangement (3) an arrangement comprises a magnetic field sensor element.
