Description

Die Erfindung betrifft eine Vorrichtung zum Nachweis eines Manipulationsversuches mit einem starken Magnetfeld an einem einen magnetisch aktivierbaren Sperrmechanismus aufweisenden Schließzylinder.The invention relates to a device for detecting a manipulation attempt with a strong magnetic field on a locking cylinder having a magnetically activated locking mechanism.

Schließzylinder mit einem magnetisch aktivierbaren Sperrmechanismus sind beispielsweise aus der DE 199 01 838 A1 bekannt. Bei diesem Schließzylinder ist ein Sperrriegel in einer Bohrung des Gehäuses verschieblich angeordnet und wird von einem Federelement in Richtung Kern vorgespannt. Der Kern weist Taschen zur Aufnahme des Sperrriegels auf. In Grundstellung des Schließzylinders wird ein mit dem Sperrriegel verbundener Anker gegen einen Elektromagneten des elektromagnetisch aktivierbaren Sperrmechanismus gedrückt. Bei einer vorliegenden Schließberechtigung wird der Elektromagnet bestromt und hält den Anker. Damit wird der Sperrriegel innerhalb des Gehäuses gehalten, und der Kern kann gegenüber dem Gehäuse verdreht werden. Bei fehlender Schließberechtigung wird der Sperrmechanismus nicht bestromt und der Sperrriegel gelangt durch die Kraft des Federelementes bei einer Drehung des Kerns in eine der Taschen des Kerns und blockiert dessen weitere Bewegung. Der magnetisch aktivierbare Sperrmechanismus weist in der Regel hochpermeable, ferromagnetische Werkstoffe mit kleiner Koerzitivfeldstärke auf. Ein solcher Sperrmechanismus ist jedoch anfällig gegenüber starken magnetischen Störfeldern, welche beispielsweise bei einem Manipulationsversuch mit einem starken Magneten eingesetzt werden könnten.Lock cylinder with a magnetically activated locking mechanism are known for example from DE 199 01 838 A1. In this lock cylinder, a locking bolt is slidably disposed in a bore of the housing and is biased by a spring element in the direction of the core. The core has pockets for receiving the locking bolt. In the basic position of the lock cylinder, an armature connected to the locking bolt is pressed against an electromagnet of the electromagnetically activatable locking mechanism. In the case of a present locking authorization, the electromagnet is energized and holds the armature. Thus, the locking bar is held within the housing, and the core can be rotated relative to the housing. In the absence of locking authorization, the locking mechanism is not energized and the locking bar passes through the force of the spring element upon rotation of the core in one of the pockets of the core and blocks its further movement. The magnetically activatable locking mechanism usually has high permeability, ferromagnetic materials with low coercive force. However, such a locking mechanism is susceptible to strong magnetic interference fields, which for example, could be used in a manipulation attempt with a strong magnet.

Aus der DE 102 30 344 B3 ist eine Elektromagnetanordnung bekannt geworden, bei der magnetische Sicherheitsmittel auf ein magnetisches Fremdfeld ansprechen und die Bewegung einer Kupplung in eine Schaltposition verhindern sollen.From DE 102 30 344 B3, an electromagnet arrangement has become known in which magnetic safety means respond to a foreign magnetic field and should prevent the movement of a clutch into a switching position.

Mit heutigen Selten-Erden-Dauermagneten können jedoch sehr große Störfelder im Bereich bis zu einem Tesla im Abstand von einigen Zentimetern erzeugt werden. Solche Felder lassen sich oft, bedingt durch die Bauart oder die Einbauposition des magnetisch aktivierbaren Sperrmechanismus nicht zuverlässig abschirmen, da zur Abschirmung eingesetzte ferromagnetische Materialien durch solche Störfelder magnetisch in Sättigung gebracht werden können.With today's rare earth permanent magnets, however, very large interference fields in the range up to a Tesla can be generated at a distance of a few centimeters. Such fields can often not be shielded reliably due to the design or the installation position of the magnetically activatable locking mechanism, since ferromagnetic materials used for shielding can be magnetically brought into saturation by such interference fields.

Daher ist es häufig wünschenswert, einen Nachweis über eine versuchte Manipulation des Schließzylinders mit einem starken magnetischen Störfeld zu führen. Der Nachweis sollte dabei bereits unterhalb jener Feldstärke ansprechen, bei welcher der Sperrmechanismus beeinflusst wird und anderseits einen entsprechenden Abstand zu in der Umgebung allgemein vorherrschenden magnetischen Feldern aufweisen.Therefore, it is often desirable to provide evidence of attempted manipulation of the lock cylinder with a strong magnetic noise field. In this case, the detection should already respond below the field strength at which the blocking mechanism is influenced and, on the other hand, have a corresponding distance from the magnetic fields generally prevalent in the environment.

Der Erfindung liegt daher das Problem zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, mit der ein Nachweis eines Manipulationsversuch zu erbringen ist.The invention is therefore based on the problem to provide a device of the type mentioned, with the proof of a manipulation attempt is to provide.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass ein Detektor an dem Schließzylinder oder in der unmittelbaren Umgebung des Schließzylinders angeordnet ist, dass der Detektor zumindest ein aus einem halbharten magnetischen Material gefertigtes Detektorelement und ein magnetisches Muster aufweist und dass sich das magnetische Muster von einem von einem starken Magnetfeld erzeugten Muster unterscheidet.This problem is inventively solved in that a detector on the lock cylinder or in the immediate Is arranged around the lock cylinder, that the detector has at least one made of a semi-hard magnetic material detector element and a magnetic pattern and that the magnetic pattern differs from a pattern generated by a strong magnetic field.

Durch diese Gestaltung führt ein ausreichend starkes Magnetfeld zu der Zerstörung des magnetischen Musters des Detektors. Zur Erzeugung des Musters kann beispielsweise das Detektorelement das Muster selbst aufweisen. Bei einem ausreichend starken äußeren Magnetfeld wird das Detektorelement ummagnetisiert und damit das Muster zerstört. Weiterhin kann das Detektorelement im entmagnetisierten Zustand eingesetzt werden und von dem starken äußeren Magnetfeld in irgend einer Weise magnetisiert werden. Als Detektor geeignete Werkstoffe sind beispielsweise Eisen-Chrom-Kobalt-Nickel-Legierungen mit Koerzitivfeldstärke im Bereich von 1 bis 60 kA/m und sind unter den Handelsnamen Magnetoflex, Sensorvac oder Semivac bekannt. Die Werkstoffe können durch weitere Zusatzelemente sowie die Verarbeitung durch beispielsweise Glühen auf einen vorgesehenen Wert der Koerzitivfeldstärke eingestellt werden, so dass am dem Sperrmechanismus des Schließzylinders nahen Einbauort des Detektors eine Störfeldstärke bereits unterhalb der zur Manipulation erforderlichen Feldstärke erfasst werden kann. Die genannten Materialien besitzen eine im Wesentlichen rechteckförmige Magnetisierungsschleife, die sogenannte b-h-Kennlinie. Der Nachweis des Manipulationsversuchs mit dem starken äußeren Magnetfeld kann durch die Änderung der Magnetisierung des Detektors nach Betrag und Richtung erfolgen, welche das Magnetfeld hervorruft. Das magnetische Muster im unveränderten Zustand und im von dem äußeren starken Magnetfeld veränderten Zustand kann beispielsweise mit einem Hallsensor oder mit einem sogenannten magnetischen Auge nachgewiesen werden. Ebenso kann der Nachweis optisch über spezielle Ferrofluidfolien erfolgen. Wird eine solche Ferrofluidfolie auf den Detektor aufgebracht, so reichern sich die in einer darin befindlichen Flüssigkeit suspendierten magnetischen Teilchen im Bereich großer magnetischer Feldstärken an und führen zu einer Verfärbung in Abhängigkeit von den unterschiedlichen Feldstärken des Detektors. Weiterhin kann der Nachweis auch durch magneto-optisch aktive Schichten erfolgen, deren optische Eigenschaften, wie beispielsweise der Brechungsindex, von der vorhandenen Magnetfeldstärke abhängt. Durch eine Beleuchtung mit polarisiertem Licht kann indirekt das Magnetfeld sichtbar gemacht werden.Due to this design, a sufficiently strong magnetic field leads to the destruction of the magnetic pattern of the detector. To generate the pattern, for example, the detector element may have the pattern itself. With a sufficiently strong external magnetic field, the detector element is re-magnetized and thus destroys the pattern. Furthermore, the detector element can be used in the demagnetized state and be magnetized by the strong external magnetic field in some way. Materials suitable as detector are, for example, iron-chromium-cobalt-nickel alloys with coercive force in the range from 1 to 60 kA / m and are known under the trade names Magnetoflex, Sensorvac or Semivac. The materials can be adjusted by further additional elements and the processing by, for example, annealing to an intended value of the coercive force, so that at the locking mechanism of the lock cylinder near installation location of the detector an interference field strength can already be detected below the field strength required for manipulation. The materials mentioned have a substantially rectangular magnetization loop, the so-called bh characteristic. The detection of the manipulation experiment with the strong external magnetic field can be done by changing the magnetization of the detector in terms of magnitude and direction, which causes the magnetic field. The magnetic pattern in unmodified state and strong from the outside Magnetic field changed state can be detected for example with a Hall sensor or with a so-called magnetic eye. Likewise, the detection can be done optically via special ferrofluidic films. If such a ferrofluid film is applied to the detector, the magnetic particles suspended in a liquid contained therein accumulate in the region of high magnetic field strengths and lead to discoloration as a function of the different field strengths of the detector. Furthermore, the detection can also be carried out by magneto-optically active layers whose optical properties, such as the refractive index, on the existing magnetic field strength depends. By illuminating with polarized light, the magnetic field can indirectly be made visible.

Die Montage des Detektorelementes erfordert gemäß einer vorteilhaften Weiterbildung der Erfindung einen besonders geringen Aufwand, wenn das Detektorelement als Detektorfolie ausgebildet ist. Die vorstehend genannten Materialien eignen sich durch ihre gute Kaltverformbarkeit zur Erzeugung von Folien vorzugsweise in einem Dickenbereich unter 100 µm und sind gegen mechanische Beanspruchung weitgehend unempfindlich.The assembly of the detector element requires according to an advantageous embodiment of the invention, a particularly low cost when the detector element is designed as a detector film. Due to their good cold workability for the production of films, the abovementioned materials are preferably suitable in a thickness range below 100 μm and are largely insensitive to mechanical stress.

Der Detektor weist gemäß einer anderen vorteilhaften Weiterbildung der Erfindung eine hohe Stabilität auf, wenn das Detektorelement als Stift oder Platte ausgebildet ist.The detector has according to another advantageous embodiment of the invention, a high stability, when the detector element is designed as a pin or plate.

Vorhandene Schließanlagen lassen sich mit der erfindungsgemäßen Vorrichtung einfach nachrüsten, wenn das Detektorelement an dem Schließzylinder, im Bereich eines den Schließzylinder aufnehmenden Schlosskastens oder einer den Schließzylinder umschließenden Rosette angeordnet ist.Existing locking systems can be easily retrofitted with the device according to the invention, when the detector element to the lock cylinder, in the region of a lock cylinder receiving the lock case or a the lock cylinder surrounding rosette is arranged.

Das Detektorelement trägt gemäß einer anderen vorteilhaften Weiterbildung der Erfindung zum Schutz des Schließzylinders gegen ein Aufbohren bei, wenn das Detektorelement im Gehäuse zwischen der Stirnseite und dem Sperrmechanismus angeordnet ist. Hierfür können beispielsweise als Detektorelement ausgebildete Stifte anstelle allgemein bekannter Bohrschutzstifte in das Gehäuse des Schließzylinders eingepresst werden. Damit ist der Detektor als Bohrschutzelement ausgebildet.The detector element contributes according to another advantageous development of the invention to protect the lock cylinder against drilling when the detector element is arranged in the housing between the end face and the locking mechanism. For this purpose, for example, pins designed as a detector element can be pressed into the housing of the lock cylinder instead of generally known drill protection pins. Thus, the detector is designed as Bohrschutzelement.

Der Nachweis des Manipulationsversuchs gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn das Detektorelement eine magneto-optische Oberfläche aufweist und an einem von außerhalb des Schließzylinders sichtbaren Bereich angeordnet ist.According to another advantageous development of the invention, the proof of the manipulation attempt is particularly simple if the detector element has a magneto-optical surface and is arranged on a region visible from outside the lock cylinder.

Der Detektor gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung konstruktiv besonders einfach, wenn das magnetische Muster des Detektors in dem Detektorelement angeordnet ist.According to another advantageous development of the invention, the detector is structurally particularly simple if the magnetic pattern of the detector is arranged in the detector element.

Das vorgesehene Musters lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung durch eine Anordnung von mehreren, verteilt angeordneten Detektorelementen mit einer vorgesehenen magnetischen Ausrichtung besonders einfach zusammenstellen. Hierdurch kann das magnetische Muster des Detektors von den selbst eine magnetische Ausrichtung aufweisenden Detektorelementen gebildet werden. Weisen beispielsweise zwei nebeneinander angeordnete Detektorelemente einander gegensinnige magnetische Ausrichtungen auf, werden die Ausrichtungen bei einem äußeren Magnetfeld beispielsweise ummagnetisiert, so dass sie gleichsinnig ausgerichtet sind. Damit werden bei der Einwirkung des starken Magnetfeldes die magnetischen Ausrichtungen der Detektorelemente geändert, womit sich ein Manipulationsversuch erfassen lässt.According to another advantageous development of the invention, the proposed pattern can be combined in a particularly simple manner by arranging a plurality of detector elements arranged in a distributed manner with an intended magnetic alignment. As a result, the magnetic pattern of the detector can be formed by the detector elements, which themselves have a magnetic alignment. For example, if two detector elements arranged next to one another have opposite magnetic fields Orientations on, the alignments are re-magnetized, for example, in an external magnetic field, so that they are aligned in the same direction. Thus, the magnetic alignments of the detector elements are changed when exposed to the strong magnetic field, whereby a manipulation attempt can be detected.

Zur Erhöhung der Zuverlässigkeit der Erfassung eines Manipulationsversuchs trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn mehrere Detektorelemente in einer Reihe angeordnet sind. Das magnetische Muster des Detektors kann dabei von den einzelnen Detektorelementen zusammengesetzt werden.To increase the reliability of the detection of a manipulation attempt, it contributes, according to another advantageous embodiment of the invention, when a plurality of detector elements are arranged in a row. The magnetic pattern of the detector can be composed of the individual detector elements.

Das Detektorelement 15 ist als Folie ausgebildet und weist ein magnetisches Muster, beispielsweise eine bereichsweise alternierende magnetische Polung auf und ist im Wesentlichen zwischen dem Sperrmechanismus 7 und der über der Tür 1 überstehenden Stirnseite des Schließzylinders 3 angeordnet. Wenn man versucht, den Sperrmechanismus 7 mittels eines starken Magnetfeldes eines vor die Tür 1 gehaltenen Magneten 16 zu manipulieren, wird das magnetische Muster des Detektorelementes 15 von dem Magneten 16 zerstört. Dieser Manipulationsversuch ist durch Messung des Musters des Detektorelementes 15 erfassbar.Figure 1 shows schematically a arranged in a door 1 lock case 2 with a lock cylinder 3 mounted therein and with a device 4 for detecting a manipulation attempt. The lock cylinder 3 has a rotatable core 5 in a housing 6 and an electromagnetically activatable locking mechanism 7. The electromagnetically activatable locking mechanism 7 controls the mobility of the core 6 relative to the housing 5 in response to a key inserted into a closing channel 8 of the core 6. He may alternatively be designed as a clutch. The locking mechanism 7 has a locking bolt 10 penetrating into a recess 9 of the core 6 and an electromagnet 11 for controlling the movability of the locking bolt 10 and is described in detail in DE 199 01 838 A1. Therefore, for the disclosure of the components and the function of the locking mechanism 7, reference is expressly made to this document. The over the door 1 protruding end face of the lock cylinder 3 is surrounded by a rosette 12. The core 6 of the lock cylinder 3 is rotatably connected to a cam 13. The device 4 for detecting a manipulation attempt has a detector 14 with a single, arranged on the outside of the lock cylinder 3 detector element 15. The detector element 15 is as a foil formed and has a magnetic pattern, for example, a region-wise alternating magnetic polarity and is arranged substantially between the locking mechanism 7 and over the door 1 projecting end face of the lock cylinder 3. When one tries to manipulate the locking mechanism 7 by means of a strong magnetic field of a held in front of the door 1 magnet 16, the magnetic pattern of the detector element 15 is destroyed by the magnet 16. This manipulation attempt can be detected by measuring the pattern of the detector element 15.

Figur 2 zeigt den Schließzylinder 3 aus Figur 1 mit der Rosette 12 in einer Ansicht auf seine über der Tür 1 überstehenden Stirnseite. In einer weiteren, nicht dargestellten Ausführungsform kann der Detektor 14 auch mehrere Detektorelemente 15 aufweisen oder auf der Rosette 12 sichtbar oder unsichtbar angeordnet sein. Denkbar ist ebenfalls die Anordnung des Detektors 14 auf dem Schlosskasten 2 oder auf der Tür 1.Figure 2 shows the lock cylinder 3 of Figure 1 with the rosette 12 in a view of its over the door 1 protruding end face. In another embodiment, not shown, the detector 14 may also have a plurality of detector elements 15 or be arranged on the rosette 12 visible or invisible. Also conceivable is the arrangement of the detector 14 on the lock case 2 or on the door 1.

Figur 3 zeigt einen Schließzylinder 17 mit einem mehrere Detektorelemente 18 aufweisenden Detektor 19. Die Detektorelemente 18 sind in einem Gehäuse 20 und in einem Kern 21 des Schließzylinders 17 angeordnet. Die Detektorelemente 18 sind als Stifte ausgebildet und können zur Erzeugung des magnetischen Musters eine unterschiedliche Ausrichtung ihrer Magnetpole aufweisen. Bei einem starken äußeren Magnetfeld wird die Ausrichtung der Magnetpole der Detektorelemente 18 geändert und kann einfach, beispielsweise durch Hallelemente nachgewiesen werden. Einige der Detektorelemente 18 sind in das Gehäuse 20 zwischen einem magnetisch aktivierbaren Sperrmechanismus 22 und einer Stirnseite eingepresst und können zudem als Bohrschutz dienen. Zur Verdeutlichung zeigt Figur 4 den Schließzylinder 17 aus Figur 3 in einer Ansicht auf die Stirnseite. Hierbei ist zu erkennen, dass die in dem Kern 21 angeordneten Detektorelemente 18 um einen Schließkanal 23 herum gruppiert sind und ebenfalls einen Schutz gegen ein Aufbohren bieten.FIG. 3 shows a lock cylinder 17 with a detector 19 having a plurality of detector elements 18. The detector elements 18 are arranged in a housing 20 and in a core 21 of the lock cylinder 17. The detector elements 18 are formed as pins and may have a different orientation of their magnetic poles to produce the magnetic pattern. In a strong external magnetic field, the orientation of the magnetic poles of the detector elements 18 is changed and can be easily detected, for example, by Hall elements. Some of the detector elements 18 are pressed into the housing 20 between a magnetically activated locking mechanism 22 and a front side and can also as Serve drilling protection. For clarity, Figure 4 shows the lock cylinder 17 of Figure 3 in a view of the front page. It can be seen here that the detector elements 18 arranged in the core 21 are grouped around a closing channel 23 and likewise offer protection against drilling.

Figur 5a zeigt ein Detektorelement 24 für den Einsatz in den Detektoren 14, 19 aus den Figuren 1 bis 4 während der Erzeugung eines magnetischen Musters. Hierfür wird ein zur Erzeugung des magnetischen Musters vorgesehener Stempel 25 mit einer Rückschlussplatte 26 und darauf angeordneten Permanentmagneten 27 mit unterschiedlichen Magnetisierungsrichtungen eingesetzt. Die Magnetpole der Permanentmagnete 27 wechseln einander ab, so dass abwechselnd der Nordpol oder der Südpol der Permanentmagnete 27 von der Rückschlussplatte 26 weg auf das Detektorelement 24 weist. Hierbei wird in das Detektorelement 24 mit einem magnetischen Muster versehen, welches beispielsweise mittels einer auf das Detektorelement 24 aufgelegten und in Figur 5b dargestellten Ferrofluidfolie 28 nachgewiesen werden kann. Die Ferrofluidfolie 28 macht das mit dem Stempel 25 erzeugte magnetische Muster durch eine unterschiedliche Verfärbung sichtbar, welche in der Zeichnung durch eine unterschiedliche Schraffur veranschaulicht ist. Bei einem Manipulationsversuch mit einem starken Magnetfeld wird das mit dem Stempel 25 erzeugte magnetische Muster zerstört, so dass die auf das Detektorelement 24 aufgelegte Ferrofluidfolie 28 eine deutlich andere Verfärbung zeigt, wie es in Figur 5c dargestellt ist.FIG. 5a shows a detector element 24 for use in the detectors 14, 19 from FIGS. 1 to 4 during the generation of a magnetic pattern. For this purpose, a provided for generating the magnetic pattern punch 25 with a return plate 26 and disposed thereon permanent magnet 27 is used with different magnetization directions. The magnetic poles of the permanent magnets 27 alternate with each other, so that alternately the north pole or the south pole of the permanent magnets 27 points away from the return plate 26 to the detector element 24. In this case, a magnetic pattern is provided in the detector element 24, which can be detected, for example, by means of a ferrofluid film 28 placed on the detector element 24 and shown in FIG. 5b. The ferrofluidic film 28 makes the magnetic pattern produced by the stamp 25 visible through a different coloration, which is illustrated in the drawing by a different hatching. In a manipulation attempt with a strong magnetic field, the magnetic pattern generated by the punch 25 is destroyed, so that the ferrofluid film 28 placed on the detector element 24 shows a distinctly different coloration, as shown in FIG. 5c.

Figur 6 zeigt mehrere, einheitlich magnetisierte Detektorelemente 29 zum Einsatz in den Detektoren 14, 19 nach den Figuren 1 bis 4. Diese Detektorelemente 29 sind in einer Reihe auf einem vorgesehenen Abstand zueinander angeordnet und erzeugen jeweils gestrichelt dargestellte Feldlinien. Die Magnetisierung und die Abmessungen der Detektorelemente 29 bilden ein magnetisches Muster, welches durch unterschiedliche Verfärbungen einer Ferrofluidfolie 30 nachgewiesen werden kann. Auch hier führt ein starkes Magnetfeld zu einer Aufmagnetisierung der Detektorelemente 29 und damit zu einer Zerstörung des Musters, wie es in Figur 5c dargestellt ist.FIG. 6 shows a plurality of uniformly magnetized detector elements 29 for use in the detectors 14, 19 according to FIGS. 1 to 4. These detector elements 29 are shown in FIG a row arranged at a designated distance from each other and each generate dashed lines shown field lines. The magnetization and the dimensions of the detector elements 29 form a magnetic pattern, which can be detected by different discoloration of a ferrofluid film 30. Again, a strong magnetic field leads to a magnetization of the detector elements 29 and thus to a destruction of the pattern, as shown in Figure 5c.

Figur 7 zeigt mehrere, in einem vorgesehenen Muster angeordnete Detektorelemente 31, welche zum Einsatz in den Detektoren 14, 19 nach den Figuren 1 bis 4 eingesetzt werden können, bei der Einwirkung eines starken Magnetfeldes eines Magneten 32. Die Feldlinien des Magneten 32 sind gestrichelt dargestellt und erzeugen eine Magnetisierung in den Detektorelementen 31, welche zur Vereinfachung durch eine unterschiedliche Schraffur veranschaulicht ist. Im Grundzustand können die Detektorelemente 31 unmagnetisiert sein. Werden die unmagnetisierten Detektorelemente 31 beim Manipulationsversuch einem starken Magnetfeld des Magneten 32 ausgesetzt, lässt sich dieser Manipulationsversuch an dem Vorhandensein der schraffiert dargestellten Magnetisierung erkennen.FIG. 7 shows a plurality of detector elements 31, arranged in a designated pattern, which can be used for use in the detectors 14, 19 according to FIGS. 1 to 4 under the action of a strong magnetic field of a magnet 32. The field lines of the magnet 32 are shown in broken lines and generate a magnetization in the detector elements 31, which is illustrated for simplicity by a different hatching. In the ground state, the detector elements 31 may be unmagnetized. If the unmagnetized detector elements 31 are exposed to a strong magnetic field of the magnet 32 during the manipulation attempt, this manipulation attempt can be detected by the presence of the hatched magnetization.
