The static geomagnetic active shielding system

The static magnetic field active shielding system can offset the magnetic field fluctuations of the geomagnetic field in real time, thereby generating a 10nT zero magnetic environment in the geomagnetic environment. For example, the gradient magnetic field of 1nT or 0.1nT can be generated in the shielding room or shielding cylinder, the system can also generate any set magnetic field in three-dimensional components for scientific experiments and simulation of geomagnetic changes.
