FIELD: measurement equipment.
SUBSTANCE: device for measurement of structure of axial-symmetrical alternating magnetic field comprises a system of measurement coils, which are arranged concentrically. Areas of measurement coils differ by a fixed value. It makes it possible to measure value of magnetic induction of alternating magnetic field in the specified plane, which is perpendicular to the axis of symmetry of the examined alternating magnetic field. To examine the structure of the alternating magnetic field, the system of measurement coils is placed on a motion screw, which with a steering wheel is moved in steps along the axis of symmetry of the examined alternating magnetic field. To indicate the axial position of the system of measurement coils, an arrow indicator and a scale are used. Efficiency of the device is tested experimentally during examination of the structure of solenoid magnetic field.
EFFECT: results of sufficiently high speed are produced.
