The performance of a parallel stream type HGMS filter using amorphous ribbons is analyzed in consideration of a neighboring wire effect on a particle capture process and an elliptic cross section of the ribbons which has a large aspect ratio, etc. The main theoretical results are: 1) the neighboring wire effect cannot be neglected in a high effective length of the filter, and 2) the effect increases the particle recovery against our conventional understanding. This reason is that the shape effect of the particle capture area dominates the magnetic force decreasing effect.Some measurements on the removal of fine magnetic particles in two types of colloid are carried out by using an amorphous ribbon filter. The experimental particle recovery agrees well with the theoretical one which is calculated by taking account of a grain size distribution in the colloid and an edge effect of the filter.
