The class of filtering magnetic structures formed by an 
ordered set of ferromagnetic microballs is considered. We develop 
an approach to the analysis of their magnetophoretic properties based 
on the dipole approach and the concept of a magnetophoretic potential 
averaged along the direction of motion of the suspension of separated 
particles. We have investigated the magnetophoretic properties of 
longitudinally and transversely magnetized linear chains of balls. 
Experiments aimed at estimating the accuracy of the dipole approximation 
have been performed.
