Abstract: The problem is considered of the moving object magnetic field control with the use of the onboard magnetic gradiometer sensors in order to minimize the magnetic influence of the object. It is suggested to solve this problem using the onboard magnetic dipoles by altering their dipole moments. To form the feedback signal in the magnetic field control loop two magnetic gradiometers should be used, installed at different distances from the carrier body. Two methods of controlling are considered. One of them uses the difference between gradiometers' readings, taking their known mutual position into account. Another is based on assumption of negligible object influence on large distances, that allows to evaluate the external magnetic field using the farther magnetic gradiometer.

Keywords: magnetic gradiometry, SQUID, degaussing.
