PROBLEM TO BE SOLVED: To improve effects of a magnetic shield while reducing weight increase due to the magnetic shield.SOLUTION: An active shield installation position determination method includes: a shield boundary surface determination step for determining a shield boundary surface enclosing an object space desired to reduce a magnetic field; a magnetic field calculation step for calculating a magnetic field that cancels the magnetic field on the shield boundary surface based on measurement data of the magnetic field; a shield current surface density calculation step for calculating a shield current surface density that is a surface density of a current to flow as a magnetic shield based on the magnetic field that is calculated in the magnetic field calculation step; and a member installation position determination step for determining an installation position of an active shield member in such a manner that the current flows in accordance with the shield current surface density.SELECTED DRAWING: Figure 8

    【課題】磁気シールドによる重量増を低減させつつ磁気シールドの効果を高める。【解決手段】アクティブシールド設置位置決定方法が、磁界を低減させたい対象空間を囲む遮蔽境界面を決定する遮蔽境界面決定ステップと、磁界の測定データに基づいて前記遮蔽境界面の磁界を打ち消す磁界を算出する磁界算出ステップと、磁気シールドとして流す電流の面密度である遮蔽電流面密度を、前記磁界算出ステップで算出した磁界に基づいて算出する遮蔽電流面密度算出ステップと、前記遮蔽電流面密度に応じて電流を流すようにアクティブシールド部材の設置位置を決定する部材設置位置決定ステップと、を含む。【選択図】図8
