Magnetic shift tracks or magnetic strips, to which application of a rotating magnetic field or by rotation of the strip itself allows accurate determination of domain wall movement. One particular embodiment is a method of determining a position of a domain wall in a magnetic strip. The method includes applying a rotating magnetic field to the magnetic strip, the magnetic field rotating around a longitudinal axis of the magnetic strip, and after applying the magnetic field, determining a displacement of the domain wall to a second position.
