摘要

The nuclear magnetic resonance device which has the magnetic field formation vessel, and this magnetic field formation vessel which are formed in the magnetic circuit of the open magnetic circuit which can form the uniform magnetic field with briefer structure is offered. As direction of magnetization is directed to reference direction, the 1st permanent magnet which is consecutively arranged across specified interval and touching the 2nd permanent magnet and with of the 1st permanent magnet and the 2nd permanent magnet, mutually in this reference direction according to reference direction, or it has with the 3rd permanent magnet and the 4th permanent magnet which consecutively it arranges across specified interval, direction of magnetization of the 3rd permanent magnet the 1st component which is parallel with reference direction and, 1st direction crossing, has with the 2nd component which it directs to territory sideIt makes direction, direction of magnetization of the 4th permanent magnet, the 1st component and, direction of the 2nd component and being backward, as the 2nd component makes the magnetic field formation vessel of the open magnetic circuit type which is made the direction which possesses the reversal 2nd component which is made the same size.
