FIELD: the invention refers to a measuring sound for receiving data about magnetization of an object (7 ) particularly of a protected document or an article holding at least one material (M) of magnetic protection. ^ SUBSTANCE: the measuring sound has a magnetizing coil (3) without a core and two magnetic sensors (4s, 4c, 8s, 8c) located inside the magnetizing coil (3) from its both ends. At that the sensors' magnetic axles are combined with the axle of the magnetizing coil (3). The invention also refers to an arrangement of identification of authenticity holding the indicated measuring sound and to a mode of identification of authenticity fulfilled with using of the indicated measuring sound and the arrangement of identification of authenticity. ^ EFFECT: the proposed mounting of a measuring sound provides reliable and quick definition of characteristics of magnetization of thin sheet materials located away of the channel of the magnetizing coil. ^ 16 cl,8 dwg
