Abstract
A magnet assembly has a generally U-shape, the bight of the U including a permanent magnet which generates a magnetic field whose flux passes through a working volume defined between the arms of the U. The dimensions of the assembly are chosen such that: ##EQU1## where: L.sub.g is the length of the gap between the arms, PA1 L.sub.m is the length of the magnet, PA1 B.sub.r is the remnant field of the magnet, and PA1 B.sub.g is the field in the gap.
