  • Tunable segmented ring magnet and method of manufacture
    Patent number: 4538130
    Abstract: A segmented permanent ring magnet which is tunable to provide a preselected transverse magnetic field within the magnet interior is disclosed. The permanent magnet is constructed of material which has essentially linear behavior in the second quadrant of the B-H curve. The invention includes a method of tuning a segmented permanent ring magnet and a method of manufacture for the blocks of magnetic material which make up the magnet. The magnets of the present invention are particularly adapted for use as bias magnets in NMR imaging systems.
