FIELD: physics.
SUBSTANCE: device has a rotating ferromagnetic ring and a resolving processor. The ring consists of the investigated ferromagnetic material and part of it is placed in the magnetic gap of an electromagnet. Input and output magnetic sensors are placed on edges of the magnetic gap of the electromagnet in the direction of rotation of the ferromagnetic ring. The magnetic sensors include inductance coils connected to corresponding first and second variable capacitors. Oscillatory circuits formed by the coils and the capacitors are part of first and second high-frequency generators.
EFFECT: high accuracy of measuring magnetic viscosity and broader functional capabilities of the device.
