A testing configuration for testing a security document includes a security element, having a high-coercivity magnetic material and a low-coercivity magnetic material, a device comprising such a test configuration and to a relevant test method. The high- and low- coercivity magnetic materials of the security element are magnetized in a first direction by the interaction of first and second magnet pair units, and subsequently the low-coercivity magnetic material is remagnetized in a second magnetization direction by means of the second magnet pair unit. The magnet pair units are arranged with respect to one another in such a closely adjacent manner along the transport path of the security document that the first magnet field strength is greater than the magnet field strength provided by the first magnet pair unit alone and is greater than the magnet field strength provided by the second magnet pair unit alone.
