FIELD: information and measurement technology, specifically, magnetometry. SUBSTANCE: technical result of invention lies in measurement of magnetic induction in one point, in securing distribution of magnetic fields in space and time and in visualization of their images with the aid of algorithm of computer tomography. Proposed gear has bus, stepping motors connected to control units, transmitting screw connected to first motor and source of emission of magnetic fields positioned on rotary table. Gear is supplemented with additional bus and two measurement circuits in the form of narrow rectangular frames orthogonally oriented one relative to another and made fast to mechanism of two-coordinate positioning. Electric outputs of circuits are connected to amplifiers which outputs are connected to inputs of two-channel analog-to-digital converter whose both output buses are linked to interface. Transmitting screw is linked to rotating mechanism which carries rotary table, second and third stepping motors connected via horizontal and vertical guides to mechanism of two-coordinate positioning. Units of limit switches which outputs are connected to interface are anchored on all stepping motors. Interface is connected by outputs to computer and to source of emission of magnetic fields via former of synchronization pulse. EFFECT: measurement of magnetic induction in one point, securing of distribution of magnetic fields in space and time and visualization of their images. 4 dwg
