Faraday current, which flows in a circumferential direction in a disk MHD generator, was successfully measured using a method of Rogowski coil. This fact allowed us to estimate the radial distributions of fluid and elecrical propreties, such as gas flow velocity, Hall parameter, electrical conductivity, from the experimental data.
In the present paper, measuring system of the Faraday current and its calibration method are described in detail. Furthermore, as an example of the experimentally estimated properties, factors governing total pressure reduction along the radial direction are shown.
