Abstract
A method of magnetizing a permanently magnetizable element associated with a magnetic field sensor structure includes generating a test magnetic field penetrating the magnetic field sensor structure and the permanently magnetizable element, detecting the magnetic field and providing a test signal based on a magnetic field through the magnetic field sensor structure, aligning the test magnetic field and the magnetic field sensor structure with the permanently magnetizable element to each other, until the test signal reaches a set value corresponding to a predetermined magnetized field distribution with respect to the magnetic field sensor structure, and generating a magnetizing field for permanently magnetizing the element to be permanently magnetized, wherein the magnetizing field corresponds to the predetermined magnetic field distribution within a tolerance range.
