要約(日本語): The concept of overcompensation was introduced earlier. The effect of overcompensation on reducing the gradient of the vertical component of magnetic field inside the separate shell magnetic shield is studied for the operation of MCG measurement sensors. The results show that slight increase in the active compensation current used is capable of eliminating the gradient of By component at the area of interest. Finally, A practical implementation is introduced to achieve overcompensation inside the shield.
