Abstract
The invention relates to a security element for protecting documents of value, which has magnetic material. A portion of a magnetic coding is arranged on the security element, which coding consists of several magnetic areas and several gap areas. The portion of the magnetic coding is arranged in a predetermined direction along the security element, for example perpendicularly to a transport direction of the security element or document of value through a magnet sensor. Concerning the length of the magnetic areas and of the gap areas of the magnetic coding, certain length conditions are predetermined, which are chosen in dependence on the magnet sensor employed.
