<p>The invention relates to a method for measuring at least one of the parameters of torsion angle, change in length, or magnetic field. To this end, a dynamic magnetization is generated according to the invention in a first conductor segment (AB) of a magnetizable or magnetized electrically conductive conductor arrangement (AD) by applying a magnetic field and applying a current impulse to the first conductor segment (AB). A magnetization is thus induced and migrates from the first conductor segment (AB) into a second conductor segment (CD) comprising a helical anisotropy (a). The anisotropy (a) allows the magnetization thus transported to be captured by means of a voltage generated across the second conductor segment due to the transport of the magnetization (9), said magnetization being a dimension for the parameter of torsion angle, change in length, magnetic field, or a mixture of a plurality of said parameters. During the measurement, at least one conductor segment (AB; AD) of the conductor arrangement is exposed to a magnetic field having a modified magnetic field strength, and the dynamic magnetization is determined at at least two different magnetic field strengths of the modifiable magnetic field. The voltages (9) thus obtained and detected at the different magnetic field strengths are used together for forming the dimension for the parameter of the torsion angle, the change in length, and/or the magnetic field. The method is suitable for producing sensors.</p> |
