Abstract

The method starts from a magnet (14) having its opposite ends magnetized such that north and south pole be equally strong. One pole (N) of the locking magnet is connected to the opposite pole (S) of a second magnet (30). A magnetic field is applied to the opposite end (S) of the locking magnet, and is collapsed to reverse the polarity of said opposite end, whereby the strenght of the magnetic pole adjacent the second magnet becomes relatively weak compared to the pole adjacent the magnetic field. Use in order to prevent undesirable interaction between the locking magnets in magnetic locksets.
