摘要： PROBLEM TO BE SOLVED: To provide an active shielding device that can obtain shielding performance over a wide frequency range even if the frequency of an external magnetic field is fluctuated, and at the same time prevents the shielding performance from easily deteriorating even if the position of the generation source of the external magnetic field changes. SOLUTION: When the external magnetic field is applied to a magnetic shielding body 3 made of a ferromagnetic material, magnetic sensors 5X, 5Y, and 5Z for detecting the size of a magnetic field merely in one direction are installed at a position (a center section on a wall surface) that can detect the synthetic magnetic field of the external magnetic field and the magnetic field due to the magnetization of the magnetic shielding body 3. Coils 6X1, 6X2, 6Y1, 6Y2, 6Z1, and 6Z2 are installed so that the magnetic field having the same direction as the magnetic-field detection direction of the magnetic sensor is generated. When the synthetic magnetic field detected by the magnetic sensor is changed, a controlling device 7 is provided, where the controlling device allows current for generating the magnetic field canceling the change to flow to the coils. In the controlling device 7, the relationship between the output of the magnetic sensor and the current that is allowed to flow to the coils is set so that the magnetic field at the center section in the magnetic shielding body is minimized.

摘要： PURPOSE:To securely select a desired leak magnetic field area and the weight of the whole magnet for electromagnetic field production corresponding to it by composing the yoke shield of the magnet by using divided shield materials which are variable in lamination quantity and only varying the number of laminated shield materials. CONSTITUTION:When the magnetic shield thickness of the yoke shield 1 is increased, the number of laminated divided shield materials 31 - 3n is only increased. Consequently, as the magnetic shield thickness is increased, the resistance value of the magnetic shield circuit composed of the yoke shield 1 becomes small and much of leak magnetic flux leaking out of the magnet 2 for electrostatic field production flows to the magnetic shield circuit. Therefore, the leak magnetic field area formed when the magnet 2 for electrostatic field production is in operation becomes small by the increase in the magnetic field thickness. The magnetic shield thickness is determined by setting operation where the divided shield materials 32 - 3n are added by, for example, one at each time according to the mechanical resisting ability of the site where the magnetic resonance device is installed. Consequently, the minimum distance to an article where the influence of the leak magnetic field from the magnet 2 for electrostatic field production needs to be evaded can be secured with the least weight of the whole magnet.
