Handheld MPI devices have promising clinical application prospects due to their portability. However, there is a lack of detailed analysis of Halbach magnet arrays, which are critical for generating field-free regions in handheld MPI system imaging. Therefore, investigating the relationship between the Halbach array configuration and the resulting magnetic field is necessary.  In this study, we modify the magnet rotation angle, magnetic field rotation angle, magnet thickness, and magnet outer radius of cylindrical magnets to vary the Halbach array configuration, and further explore and confirm their relationship with the magnetic field gradients. In the future, these results can be utilized to adjust the configuration of the Halbach magnet array to better meet clinical requirements and further promote the application of handheld MPI.
