【発明が解決しようとする課題】漏洩視界は強いので、
所定距離以内には無意識に人間が近付かないようにして
いる。また、磁界に敏感な機器は近くに置けない。Since the leakage view is strong,
It prevents humans from approaching unconsciously within a predetermined distance. Also, devices that are sensitive to magnetic fields cannot be placed nearby.

上配置することが不可能な場合もある。[0004] Recently, it is not uncommon that a plurality of SCM-NMRs are installed in one room, but two SCM-NMRs are installed.
Since the NMR must be arranged at a predetermined distance or more, the use efficiency of the room is extremely low. In a small room, it may not be possible to arrange two or more units.

る。In the installation method of the present invention, the excitation directions of the magnets of the nuclear magnetic resonance apparatus are reversed, so that in the space between the two magnets, the leakage magnetic fields from the respective magnets cancel each other. Then, the combined magnetic field strength becomes extremely weak.

る。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG.
Is an embodiment of the present invention. In the drawings, reference numerals 1 and 2 respectively denote superconducting magnets of a nuclear magnetic resonance apparatus. Arrows A and -A indicate the directions of the static magnetic fields generated by the respective magnets, which are opposite to each other as can be seen from the drawing. Each magnet can switch the direction of the excitation current to the superconducting coil in the forward or reverse direction so that a static magnetic field in the direction opposite to the direction of the static magnetic field generated by the adjacent magnet can be generated. .
【0009】図2のように2台の超電導磁石の発生する
静磁場の方向を互いに逆方向にすると、2台の磁石の間

鳴装置を配置することが可能となる。As shown in FIG. 2, when the directions of the static magnetic fields generated by the two superconducting magnets are opposite to each other, the leakage magnetic fields from the respective magnets cancel each other in the space between the two magnets. As a result, the combined magnetic field strength becomes extremely weak. Therefore, even if two nuclear magnetic resonance apparatuses are arranged close to each other, a device sensitive to a magnetic field can be placed between them.
The use efficiency of the room is improved, and a plurality of nuclear magnetic resonance apparatuses can be arranged in a small room.
【0010】なお、3台以上の場合には、図3に示すよ
