摘要： The invention concerns a device and a method for examining magnetic properties of objects, in particular of sheet material such as for example bank notes. Therein the invention proceeds from a device (1) and a method for examining magnetic properties of objects (BN), in particular of sheet material such as for example bank notes, with a magneto-optical layer (42) having magnetic domains, the optical properties of the magneto-optical layer (42) being influenceable by the magnetic properties of the object (BN) to be examined, at least one light source (2) for the generation of light incident upon the magneto-optical layer (42), and at least one sensor (6) for the reception of light which is transmitted and/or reflected by the magneto-optical layer (42), with a magnetic field (B∥) in the area of the magneto-optical layer (42) which extends substantially parallel to the surface of the magneto-optical layer (42).
