FIELD: measurement equipment.
SUBSTANCE: device is proposed to measure dynamic distribution of ferromagnetic magnetic susceptibility. A ferromagnetic is made in the form of a ring, with its edge placed into a magnetic gap of an electromagnet and rotates from a synchronous electric motor. The device comprises a magnetic sensor with a winding, which creates an oscillating circuit of a high-frequency generator with a tuned capacitor connected to it. The generator output is connected to the first input of a mixer, a tuned frequency reference generator output is connected to the second input of the mixer.
EFFECT: higher accuracy of automated process of measurement of dynamic distribution of magnetic susceptibility of a ferromagnetic inside a magnetic gap along its length and evaluation of homogeneity of its magnetic properties.
