Abstract
A uniform magnetic field generating device for generating a uniform magnetic field such as that required in a nuclear magnetic resonance device is disclosed. In prior art devices, in order to obtain a highly uniform magnetic field space, a parallel gap has been formed between pole pieces which were magnetically homogenized and mounted on magnets coupled by a yoke. In place of such pole pieces, a magnetically homogenized pole block or a pole block sandwiched by pole pieces is inserted between the magnets and a cylindrical hole or space is formed in the pole block, a sectional area of the space taken in parallel with the direction of a magnetic field due to the magnets and perpendicular to the axial line of the space being of circular, ellipse or rectangular shape, whereby a highly uniform magnetic field space is established.
