Analysis of the influence of alternating magnetic field on hemispherical resonant gyro forcer

The influence of alternating magnetic fields on the hemispherical resonant gyro is analyzed. Firstly, the structure and working principle of HRG forcer system are expounded. Secondly, electromagnetic field between the exciting electrodes are analyzed in detail based on Maxwell Electromagnetic Theory. Finally, the influence of the external alternating magnetic field on exciting electrodes is discussed. It can be proved that the hemispherical resonant gyro is quite capable of good magnetic resistance ability through numerical calculation.
