ABSTRACT:
An imaging apparatus, such as an MRI system, contains at least one layer of soft magnetic material between the yoke and each permanent magnet. This imaging apparatus may be operated without pole pieces due to the presence of the soft magnetic material. The permanent magnets may be fabricated by magnetizing unmagnetized alloy bodies after the unmagnetized alloy bodies have been attached to the yoke.
