Abstract: The magnetic device is the key part of the nuclear magnetic resonance imaging instrument (NMR-CT). We designed this device by computer aided design and then constructed the imitative device. Experiments show that the difference between the calculation and measurement is only 5.1%, and the field homogeneity is about 2088×10-6.

Key words: nuclear magnetic resonance imaging, magnetic torque, field homogeneity, permanent magnet
