Abstract :
To obtain sensor sensitivity to the real weak magnetic field intensity in field so that it can be used in hybrid-source magneto tellurics, a kind of indoor calibration method of magnetic sensor is introduced. In this paper, with calibration conditions being satisfied, a calibration system was designed and results error was analysed. Because of the power-line disturbance, magnetic shielding and its influence to the calibrating precision are introduced.
