After magnetization of all magnetic materials or the magnetic regions formed therefrom in one direction with a first magnetic field region, only the low-coercivity magnetic material is remagnetized in another direction in a subsequent second magnetic field region. Magnetic signals of the magnetic regions are captured while the security element is still subjected to the second magnetic field region. On the basis of the signals all three types of magnetic region can be reliably distinguished."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Check of a security element furnished with magnetic materials","description":"Checking of security elements for value documents, which have a plurality of magnetic regions, includes at least a high-coercivity magnetic region having a high-coercivity magnetic material, a low-coe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9703994","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
