Abstract
The present invention discloses a method for reactivating a magnetic detection tag, which comprises exposing a magnetic detection tag having a soft magnetic substance layer and a hard magnetic substance layer, to an alternating magnetic field generated by applying an AC power to a coil, moving, in this state, either or both of the magnetic detection tag and the alternating magnetic field, thereby sweeping the magnetic detection tag in the alternating magnetic field to demagnetize the magnetized hard magnetic substance layer of the magnetic detection tag; and a machine for reactivating a magnetic detection tag.
