How do you demagnetize a magnetic strip?
To activate a magnetic security strip so that it can be detected, the strip must be demagnetized so that it has little or no residual magnetism.
Typically, this is done by applying a sufficiently strong alternating magnetic field to the strip, and gradually decreasing the strength of that field..
