| Abstract: | In the state of application of force, in order to increase the precision and to reduce the leak-flux of voice coil motor, numerical value calculation of magnetic field of the voice-coil motor with added steel ring shielding magnetism on two sides of magnet steel was carried out in this paper. The result shows, leak-flux would be weakened by selecting suitable thickness of the ring shielding magnetism. |
