A method for constructing a permanent magnet assembly by using a non-magnetic frame between individual magnet segments to restrain the movement of the magnet segments. The frame restricts the movement of the magnets during assembly. The frame also provides an effective system for replacing magnets in the existing assembly.

Method for constructing permanent magnet assemblies

A magnetic circuit is shaped to generate an essentially uniform magnetic field parallel across the length of a container, and an essentially uniform magnetic field gradient along the length of the container as well. The dot product of the magnetic field and magnetic field gradient, known as the relative force density, is substantially uniform over the entire container, thereby causing particles to uniformly separate throughout the container.
