Regula released a new device designed for examination of magnetic security features in documents and banknotes — magneto-optical hysterisigraph MOHyster Regula 7708.

The key feature of this unrivalled Regula solution is the possibility to measure and evaluate magnetic hysteresis characteristics of security features in documents and banknote under different magnetization conditions, namely:

  • saturation field intensity;
  • saturation magnetic induction;
  • residual magnetic induction;
  • coercive force;
  • hysteresis loss.

Based on coercive force measurements, the device allows classifying magnetic security features in documents and banknotes by the type of ferromagnetic materials they contain (i.e. Soft, SemiHard, LoCo Hard / HiCo Hard).

Hysterisigraph performs the function of magnetic field tomography at various distances from an examined object surface. This function allows studying 3D distribution of the magnetic field and its integral assessment. The device with such functionality has no analogues in the world.

MOHyster Regula 7708 is specifically designed to be used in applied research, particularly for the development of new and improvement of currently existing document security features with magnetic properties. The solution is also perfect for monitoring the quality of security features during the production of banknotes, securities and blanks. Finally, MOHyster can be used for extensive research on magnetic printing elements performed by forensic experts.

Evaluation of hysteresis parameters:
(1) Hs — saturation field intensity
(2) Bs — saturation magnetic induction
(3) Br — residual magnetic induction
(4) Hc — coercive force
(5) W = ∫ BdH — hysteresis loss
