ABSTRACT:
Static magnet pole tips for a MRI system in which the static magnet pole tips are cut from a slug of spirally wound ferromagnetic material. The static magnet pole tips are cut from the spirally wound slug such that the static magnet pole tips have no or few semi-closed loops of ferromagnetic material. The static magnet pole tips can be used individually, or can be stacked for strength and symmetry.
