STUDY ON THE MAGNETIC FIELD OF MHD ANGULAR RATE SENSOR

MHD angular rate sensor（MHD-ARS） is the main instrument for the satellite’s angle micro-vibration measurement,in this article,author compare two kind of MHD ARS,consider the radial mode MHD-ARS is the more suited sensor for our space development.Author also design the configuration of radial mode magnetic field,and obtain the needed magnetic flux density,the test result is similar with the simulation,this work is the basic approach for MHD-ARS.
