摘　　要：According to the magnetic circuit design theory and performance requirements of magnetic field, an H-type permanent magnetic actuator that generates uniform magnetic field larger than 0.4 T in the interested re- gion has been designed in this paper. The static magnetic field simulation analysis was done by Ansoft＇ s Max- well three-dimensional （3D） software. The simulation results showed that the magnetic field of this system can meet the requirements, and this permanent magnetic actuator designed in this paper can be used in small nuclear magnetic resonance （NMR） svstem.According to the magnetic circuit design theory and performance requirements of magnetic field,an H-type permanent magnetic actuator that generates uniform magnetic field larger than 0.4 T in the interested re-gion has been designed in this paper.
