The sensitivity analysis of the PPM stack with notched magnet
A periodic permanent magnet (PPM) stack with notched magnet is discussed in this paper. A fully three dimensional (3D) magnetic focusing simulator (MFS) has been used to model the PPM stack with notched magnet. The influence of changing notched size of magnet is shown by MFS. And the influence of changing material's coercive field is also shown by MFS.
