Beschreibung
Zusammenfassung:	The invention relates to a security element for protecting documents of value, which has magnetic material. Furthermore, the invention relates to a document of value, a transfer material and method for producing such security elements and documents of value as well as a method and an apparatus for checking such a security element or document of value. According to the invention the security element has at least two magnetic materials, wherein the magnetic materials have different coercive field strengths and are applied onto and/or incorporated in the security element in such a manner that their remanence is equally high.
