Abstract
A magnetic detection system for authenticating a document includes a first magnetic scanhead adapted to create a first magnetic field for saturating the magnetization of an area on each of the bills. The magnetic detection system further includes a second magnetic scanhead with an electromagnet. The electromagnet is capable of creating a second magnetic field of adjustable intensity. The second magnetic field is the opposite polarity of the first magnetic field. The intensity of the second magnetic field is adjusted by changing the amount of current supplied to the electromagnet. The amount of current supplied to the electromagnet is based upon a characteristic of the document to be authenticated.
