Abstract:

A new exciting method of the sensor in the saturated magnetemeter’s is presented n this paper，The fractional error and the absolute error of second harmonic volt in measuring coil can be decreased by employing symmetric trigonometric wave to excite it. And the saturated magnetometer can be used to survey power magnetic field strength.
