ABSTRACT:
A magnet device has main coils in a pair positioned facing each other to form a static magnetic field space in between and external magnetic flux shielding coils placed coaxially to the main coils. The external magnetic flux shielding coils have a first coil group having a small coefficient of coil coupling and a second coil group having a coefficient of coil coupling greater than that of the first coil group. The first coil group is connected in series to the second coil group. External magnetic flux entering the magnetic field imaging space formed by main coils in a pair positioned facing each other is effectively warded off.
