Abstract The existence of magnetic medium in the space around the magnet will change the distribution of magnetic field around the magnet，in this paper，the annular bonded Nd-Fe-B magnet is taken as the object of study. Through finite element analysis method，the paper analysis the influence of different Dimensions of annular medium on magnetic properties of annular bonded NdFeB magnet. By reasonably choosing the structure of the ring for gathering magnetic field，the magnetic field around the magnet can be concentrated at specific points，and the utilization ratio of magnetic properties of the magnet can be improved.

Key words： ring for gathering magnetic field working air gap magnetic field utilization ratio of magnetic property
