DEVICE FOR DETERMINATION OF MAGNETIC PROPERTIES AND METHOD OF DETERMINATION OF MAGNETIC PROPERTIES Russian patent published in 2017 - IPC G01R33/12 

FIELD: physics.

SUBSTANCE: device contains a magnetic detector module that creates a magnetic displacement field on the transport path. The direction of this magnetic field is inclined at a given angle to the transport surface for a sheet of paper. The module detects the magnetic charge of magnetic materials by detecting variations in the magnetic displacement field. The device also includes a magnetization module that is located upstream of the magnetic detector module in the indicated direction of travel and magnetizes the magnetic materials by creating a magnetic field of magnetization in the transport path, oriented in a direction different from the direction of the magnetic displacement field. In a position where the magnetic detector module detects magnetization, the magnetic materials are in a state in which magnetic materials are magnetized in mutually different directions in accordance with their coercive force.

EFFECT: creation of a small-sized device that can detect several types of different materials.
